Stepper Gear Motor

The geared stepper motor is a combination of stepper motor and gearbox. As we know, the brush DC motor will keep rotating if connected to a DC power supply. Things are different for geared stepper motor. It will convert the input pulse into a precisely defined increment in the shaft position. The shaft is moved by each pulse with a fixed angle. That means every pulse inputs, the rotator will move a step or rotate at a fixed angle. The rotating speed is proportional to the pulse frequency. Therefore, you can control the rotating speed by changing the frequency of the input pulse, realizing precise positioning.

There are various standards when it comes to categorizing the stepper gear motors. They can be divided into three types according to magnet force source: permanent magnet stepper, variable reluctance stepper, and hybrid synchronous stepper. If classified by the gearbox of stepper gear motors, stepper planetary gearbox is the most common one. The ZHAOWEI stepper gearmotors generally adopt high torque micro stepper motor with planetary gearbox, whose OD varies from 3.4mm to 38mm. Voltage: 1.5-24V, power: 0.01-40W, output speed: 5-2000rpm and output torque: 1.0 gf.cm -50kgf.cm.

Adding a gearbox to a stepper motor system can improve motor performance by reducing the inertia ratio of the load to the motor, increasing the load torque, and reducing motor oscillation. The stepper gearbox system shows significantly less vibration than the stepper motor without gearbox, especially at low speeds in the resonance frequency range. With the light weight and cost-effective structure, the small stepper motor with gearbox is suitable for various applications,like smart home devices, automobile components, consumer electronics, etc.
