How to connect the single-bridge Gantry Crane motor cut-off switch?
The wire connection of the flame-out limiting device is generally as follows: the flame-out limiting device has a total of five wires. The B stage is the common wire. The terminal on one side of the push rod is connected to the rising contactors AC phase, and the other side is connected to the falling contactors AC phase wire. Specifically, in the circuit, the appropriate place in the motor control circuit was disconnected (for example, at the relevant place of the positive and negative rotation circuit), and the 1, 4, 2, and 5 of the flame-cut limit were connected to the disconnected place respectively, and the motor input wire was connected to 6 and 7. However, it should be noted that the terminal numbers of different manufacturers may be different, but the principle is the same. If the connection position is reversed, when the upper limit push rod contacts the cut-off limit, the electric gourd can still rise but not fall. On the contrary, when the lower limit push rod contacts the cut-off limit, the electric gourd can still fall but not rise. Read more exciting novels for free
How to connect the single-phase fan motor winding
For the single-phase fan motor winding connection, the first thing to do was to determine the main and auxiliary winding of the motor and the common wire. The resistance between the three wires of the motor could be measured by a Multimeter. Three different resistance values would be obtained. The two wires with the highest resistance value were the sum of the resistance values of the main and secondary winding, and the remaining wire was the common wire. Then, the common wire was used to measure the resistance of the main and secondary winding respectively. The lower the resistance, the main winding would be the main winding, and the higher the resistance, the secondary winding would be the secondary winding. If it was a three-wire motor, the resistance between the two could be measured by a Multimeter. The two wires with the largest resistance were connected to the capacity, and the remaining wire was connected to the neutral line of the power supply. Finally, the direction of the motor could be adjusted by connecting the live wire to any one of the two capacity wires. If it was a 5-wire motor, black and yellow would be a group, and red, white, and blue would be a group. The black and yellow wires were connected to the power supply, while the yellow wire was connected to the power supply. Red, white, and blue corresponded to the three speeds. Red corresponded to fast speed, white corresponded to medium speed, and blue corresponded to low speed. There was another method of connection: the live wire was divided into two paths, one path to the main winding and then back to the neutral line, and the other path to the secondary winding and back to zero. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single-phase 15,000 W motor with a large capacity
For the choice of 15kW-single-phase motor, the first thing to do was to determine the type of the motor. Generally, the choice could be an Electrolyte or Metal Film Condenser, which was suitable for high-power single-phase motor. Then, through the formula,(C = I / (2 Pi f Delta V)/), where/(C/) represents the size of the capacity.(Unit is Farad [F]),[I] represents the current when the motor is running (Unit is Ampere [A]). According to experience, 1,000,000 volts is about 6A, and 15,000,000 volts is about [15×6 = 90A].[F] represents the frequency of the power supply (Unit is Hertz [Hertz]), and [Delta V] represents the difference between the rated voltage of the voltage and the power supply voltage (Unit is Volts [V]). At the same time, for the 1. 5kW-single-phase motor, the operating capacity should be 45 - 60uF, and the starting capacity should be 100 - 250uF times of the operating capacity. According to experience, the operating capacity of the 1kW-single-phase motor should be 30 - 40uF, and the starting capacity should be 2 - 4 times of the operating capacity. It can be used as a reference for the selection of the 15kW-single-phase motor. In addition, the voltage endurance value of the capacity is greater than or equal to 1.5 times the power supply voltage. Generally, 400V/450V is selected. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to measure the motor resistance of a single-phase pump?
For the measurement of the single-phase pump motor resistance, the following methods can be used: cut off the connection UA, and use a 1-ohm-block Multimeter to measure the starting winding U1 and U2. The resistance should be about 5 to 10 ohm-blocks. If the resistance value is greater than 1k, the winding will be burned out. Then, measure the main winding V1V2, and its resistance value is dozens of Ohms. Then measure the main and auxiliary winding U1V1, which should be infinite normally. If there is a resistance value, it means that the main and auxiliary winding has a short circuit phenomenon. After that, you need to check whether the charging and discharge of the capacity is normal. In addition, the normal resistance range of a single-phase motor is usually between 5 - 50 Ohms, and the specific range needs to be determined according to the motor model and power. You can use a Multimeter to adjust the resistance gear. The two leads of the motor can be connected to the two test pins of the Multimeter for testing. If the resistance of the motor is within the normal range, the reading of the Multimeter should be between 5 - 50 Ohms. If the resistance is abnormal, you should check whether the motor's transformer and starting circuit are normal. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to measure the coil resistance of a single-phase motor
The following methods can be used to measure the coil resistance of a single-phase motor: 1. ** Preparing Work ** - First of all, the single-phase motor's power supply was disconnected, and the voltage of the electric current was discharged to ensure safe operation. - Choose a suitable ohmmeter (Multimeter ohmmeter) and select the range according to the actual situation of the motor. 2. ** Measuring Operation ** - A single-phase motor usually leads out three wires, which can be marked as 1, 2, 3. Use the ohmmeter (when the power is low, the ohmmeter can be appropriately increased) to measure the three wires in pairs, namely, measure the three sets of resistance values of the wires. Under normal circumstances, the measured resistance was 1 large and 2 small. - You can also connect the two poles of the ohmmeter to the two winding terminal of the single-phase motor and record the measured resistance value. When measuring, the starting winding resistance of the single-phase motor should be measured first, and then the working winding resistance should be measured. When measuring the resistance of the starting winding, the working winding should be disconnected from the reactor. 3. ** Judgement of results and precautions ** - When the two sets of small resistance values are equal to the largest resistance value, it proves that the motor coil winding is normal; when the two sets of small resistance values are not equal to the largest resistance value, it proves that the motor is damaged. If the measured resistance is infinitely large, it proves that the motor winding is broken and damaged. - During the measurement, pay attention to the connection of the ohmmeter's poles to ensure that they are correct. At the same time, pay attention to the measurement accuracy to avoid excessive errors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Method for connecting single-phase motor to starting capacity
The following are some ways to connect a single-phase motor to the starting capacity: 1. ** Connection according to resistance value **: connect the two wires with the largest resistance value to the voltage, and connect the two wires with the smallest resistance value to the power supply. For example, the red and yellow wires were connected to the electric capacity, and the red and blue wires were connected to the power supply (the red and blue and yellow and blue winding values were not equal, and the motor could not be used for positive and negative rotation). 2. ** Connecting according to the letter of the binding post **: The letters U1 and U2 of the binding post are connected to the two outgoing lines of the running winding, V1 and V2 are connected to the two outgoing lines of the centrifugal switch, W1 and W2 are connected to the two outgoing lines of the starting winding, and the starting capacity is connected to W1 and V2. After connecting U1 and W2 with the connecting piece, connect them to a power cord. After connecting V1 and U2 with the connecting piece, connect them to another power cord. 3. ** For the double-value capacity motor **: The double-value capacity induction motor has a starting capacity and a running capacity. The two capacity are connected in parallel and then connected to the starting winding. 4. ** Consider the positive and negative connection **: The starting capacity is connected in parallel to the main winding and the secondary winding (the two wires with the largest resistance value among the three wires). One of the two wires is connected to the power supply line, and the common end is connected to the power supply neutral line. If this rotation is recorded as positive rotation, then when the line is connected to the other wire of the starting capacity, it is reversed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single-phase motor how to match the formula of the capacity
There are several formulas for the matching of single-phase motor with the following: 1. Calculating the working capacity according to the power: \(GC = 1950I/U\cos_\)(microfarad),\(I_) is the motor current,\(U_) is the single-phase power supply voltage, and\(\cos_\) is the power factor (take\(0.75_)). If the single-phase power is taken as\(220Vdm_), then\(GC = 1950P/(U ^2)\cos_= 1950*P/(220*220)*0.75 = 0.03*P(uF), and\(P_) is the motor power. After calculating the working capacity, the starting capacity shall be taken as 1 - 4 times of the working capacity. 2. <<C = 2 <fL>/<^2>>, where <C> is the capacity of the transformer,<f> is the frequency of the power supply,<L> is the induction of the motor, and <<^2>> is the power factor. 3. When the transformer is damaged and the labeled parameters are unknown, it can be selected according to the calculation of C = 8fs (uF), where C is the matching capacity (unit is microfarad); J is the current density of the motor starting winding (generally choose 5 - 7A/square); s is the cross-section area of the starting winding wire (square). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
