Classification of stepper motor reducers

Classification of stepper motor reducers

When the stepper motor requires high torque at low speeds, we will choose the reducer. The speed is reduced by a speed reducer with a certain reduction ratio, and the torque is increased by a certain ratio. The speed reducer is a mechanism that uses a gear speed converter to decelerate the number of revolutions of the motor to the required number of revolutions and obtain a large torque. Then the classification and selection of the reducer is very important.

 

Turbine worm reducer for stepping motor

The characteristics of the worm gear reducer are relatively large in size and compact in structure. It can be self-locking under certain conditions, and the efficiency is relatively low, about 60%. Because the efficiency is relatively low, it can't be satisfied in many occasions. It is generally not recommended to be used with stepper motors.

 

Planetary reducer for stepper motor

The planetary reducer planet, as its name implies, rotates around the star, so the planetary reducer is like this, with three planetary gears rotating around a sun gear. Planetary reducer has the characteristics of high strength, small volume, low noise, low price, large transmission torque and high service life, and the transmission efficiency is high, about 80%. The closed-loop stepping machine and the planetary reducer are widely used in the fields of textile, packaging, pharmaceutical, paper, woodworking, electronic instrumentation, medical, environmental protection and other mechanical equipment. The Closed-loop integrated stepper motor and deceleration machine provides optimized industrial solutions. To help equipment optimization in various industries.

Harmonic reducer for stepper motor

The harmonic reducer is mainly composed of four basic components: wave generator, flexible gear, flexible bearing and rigid gear. The harmonic drive reducer is a kind of flexible bearing assembled by the wave generator to make the flexible gear produce controllable elastic deformation. And meshes with the rigid gear to transmit motion and power. It features high reduction ratio, small backlash, small size and high efficiency, but it is expensive and suitable for demanding equipment.

 

In general, stepper motors are recommended for use with planetary reducers. For example, the closed-loop integrated stepper motor is used on papermaking equipment. It can be used stably under long-term high-speed operation, giving customers a “zero defect” experience.
