Gear Motor’s Characteristics and Application

The gear motor is generally used for low speed and large torque transmission equipment which is to decelerate the high-speed working equipment through the input shaft of the speed reducer’s less-teeth gear less engages with the output gear axle. Gear motor 60KTYZ-2 is a synchronous motor which is incorporated by a permanent magnet synchronous motor and a retarding mechanism.

Gear Motor

With small power consumption, large torque, low noise, small size, light weight, convenient use, it can remain stable and the motor speed can not be influenced by voltage in the rated frequency. If the gear motor overload or stall when it loads, motor coil will not be burned. Gear motor is mainly applied to monitor the PTZ, electric appliance, cooling- heating valve, automatic instrument, electric model, electric advertisement, mahjong table, screen machine, laminator, currency-counting machine, barbecue equipment, display cabinets, hot dog machine, electric apparatus and all small subpoena power and low constant speed running equipment.

AC Motor’s Operating Principle

Actually, AC motor is everywhere in our life. For example, it is widely applied in the lampblack machine, washing machine, vacuum cleaner, electric fan, ventilator, hairdryer and etc. How does it work? Take single-phase AC motor, one type of the AC motors, for instance. Single-phase AC motor has two windings, the starting winding and the running winding. The starting winding is connected in series on a large capacitor. When the running winding and the starting winding go through the single-phase alternating current, it reached the maximum value because the capacitor makes the current in the starting winding has an angle of 90 degrees ahead of the running winding in time. Then the same two pulse magnetic fields are formed in the time and space so that a revolving magnetic field is generated in the air gap between the stator and the rotor. In the effect of revolving magnetic field, induction current is produced in a rotor. In the meantime, with the electromagnetic torque produced by the interaction between revolving magnetic field and current, the motor rotates.
