Precautions for wiring of gear reduction motor

Gear reduction motor is widely used in industries such as steel, textile, metallurgy, and automation machinery. It is composed of a motor and a gearbox, and the output torque drives the mechanical device to work. It has the characteristics of low noise, high reliability, simple structure, and long service life.

The purpose of a gear reducer is to reduce the speed of the motor when it starts. Only when the speed of the motor decreases, the current decreases when the motor starts running, making it easier for the motor to rotate. If the motor is connected to a power source and runs quickly, high current can easily cause the inner coil to heat up, and severe heating can damage the coil. We all know that the gears of a reducer motor must have multiple gears to move. Using a small gear to drive the large gear for operation, although the motor is running at high speed, after step-by-step deceleration, the final output gear speed is greatly reduced. The torque will increase as the speed decreases. If the motor is connected to AC power, the positive and negative poles can be ignored, which is the wiring sequence of some neutral and live wires. However, if the capacitor is connected to the motor, the other end of the capacitor should be connected. Power supply.

There are many wiring methods that can be used for precision gear reduction motors, but I need to pay attention to them when wiring to ensure safety and correctness. First, we need to confirm with the nameplate manufacturer and determine the connection method of the wires based on the motor model and winding. Before wiring, the power must be cut off to avoid the risk of electric shock. If it is impossible to determine whether to cut off the power, an electric pen can be used for testing. The insulation resistance of the motor should be checked to see if it is normal. If the insulation resistance is too small, it should be checked in a timely manner. The starting and braking wires should be connected correctly to the corresponding control device to avoid short circuit damage to the circuit. Check whether the casing and grounding cable are good to ensure reliable grounding. Accurately identify each winding group in the motor and check. Whether the coil is burnt or short circuited, Follow the correct wiring sequence, starting from the positive pole of the power supply, connect the components one by one according to the circuit diagram, and then proceed with the actual connection after completing the circuit diagram. Ensure good contact between the cable and the interface, and avoid poor contact, looseness, and other phenomena. Check whether the conductive parts are wrapped in the insulation glue on the wiring board. When wiring, strictly follow the circuit diagram to ensure reliable connection. After wiring is completed, use a measuring instrument or multimeter to measure and confirm whether the motor is normal.
