What’s the motor?
|A motor is a device that converts electrical energy into mechanical energy. It uses the energized coil that it is the stator winding to generate a rotating magnetic field and acts on the rotor such as a squirrel-cage closed aluminum frame to form a magnetoelectric rotary torque. The motor is mainly composed of a stator and a rotor. The direction of the force-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux (magnetic field direction). The working principle of the motor is the effect of the magnetic field on the force of the current, which causes the motor to rotate.|
The use and control of the motor is very convenient, with self-starting, acceleration, braking, reversing, choking and other capabilities, can meet a variety of operational requirements; motor work efficiency is high, there is no smoke, odor, no environmental pollution, noise Also smaller. Because of its series of advantages, it is widely used in various aspects such as industrial and agricultural production, transportation, national defense, commerce and household appliances, and medical electrical equipment.
During the long-term operation of the motor, various faults often occur. For example, the torque transmitted by the connector between the gearhead and the reducer is severe, and the connection hole on the flange surface is seriously worn. This increases the connection gap of the connection and leads to transmission. The torque is not smooth; the bearings of the motor shaft are damaged after the bearings are damaged; the shaft head and the keyway are worn out. The application of polymer material repair has no effect on the thermal stress of the repair welding, and the repair thickness is not limited. At the same time, the metal material possessed by the product does not possess the concessional property, it can absorb the impact shock of the equipment, avoid the possibility of re-wear, and prolong the equipment.
