Torque motorAnd reducer is widely used in transmission equipment in the two kinds of motor, in the structure, principle, specifications, performance characteristics, uses, technical parameters and other aspects are different, the following Senli motor small series of these two devices are introduced in detail:
A torque motor is a motor with a special function that can continue to operate at a low speed, even when the motor is locked and the rotor cannot turn, it will not cause damage to the motor. In this mode of operation, the motor provides a stable torque to the load. Torque motors can also provide torque in the opposite direction, and the shaft output power of the torque motor is not constant power but constant torque.
The structure of the torque motor is regarded as the motor after torque optimization. The difference between torque motors and general motors is that the torque is large and the heat dissipation performance is good. Therefore, they can work properly in the case of motor occlusion and high current output.
Torque motors generally use DC brushless motors, and sometimes switch reluctance and induction motors. Since there is no standard torque motor, they become low-speed or high-torque motors.
The structure of torque motor is circular, which can be divided into rotor motor with the outer ring of the rotor, inner motor with the stator motor, inner motor with the outer ring and inner motor with the rotor. The same size, the external rotor can produce a larger torque, so the external rotor motor is more commonly used.
Some torque motors are called finite Angle motors or swing motors, which can only work at a certain Angle and cannot be fully turned. Linear motors also take into account the torque introduced by linear motors.
The classification of torque motor: DC torque motor, AC torque motor, DC brushless torque motor.
The principle of torque motor, in the constant torque characteristic torque motor can keep the torque constant in the large speed range. It is suitable for transmission occasions requiring constant torque when changing speed.
The reducer motor refers to the gear motor body integrated with the reducer motor and the motor. This integration is also known as the gear motor or gear motor, generally has a special reducer, integrated assembly, motor integration supply.
Function of reducer:
1, Decelerate while increasing the output torque. The torque output ratio is the motor output multiplied by the reduction ratio, but must not exceed the rated torque of the reduction gear.
2, The inertia of the load that is simultaneously reduced by deceleration, the inertia is the square of the deceleration ratio. Generally, it is the inertia value of the general purpose motor.
Principle: Generally through the motor, internal combustion engine or other power, through the high-speed operation of the gear reducer or the input shaft gear of the reducer to drive the big gear, to achieve a certain deceleration effect, and then use a multi-level structure to reduce the speed and reduce the output torque.
According to the transmission mode, the reducer is divided into gear motor, turbine motor and planetary gear reducer. According to the different transmission series can be divided into single-stage gear motor and multi-stage gear motor.
According to the shape of the gear can be divided into cylindrical gear reduction motor, bevel gear reduction motor and bevel gear reduction motor. According to the transmission layout, the expansion of the gear motor, the split gear motor and the coaxial gear motor. According to the drive motor can be divided into DC reducer, stepping motor, servo motor and so on.
