Harmonic Reducer: Global and Chinese Harmonic Reducer
Harmonic reducer is a precision transmission device that uses flexible wheels, rigid wheels, and wave generators to mesh with each other and generate controllable elastic deformation to transmit motion and power. Its working principle is based on the transmission theory of elastic waves. Through a wave generator, the flexible wheel produces controllable elastic deformation, forming misaligned teeth in the tooth profile, thereby achieving the effect of reducing speed and increasing torque. Harmonic reducers are widely used in industrial robots, precision machinery, aerospace and other fields due to their high reduction ratio, small and lightweight design, high rotational accuracy, and fast response.

The stepper motor itself has a holding torque, which can be used to lock the motor when powered on, equivalent to braking. But if the holding torque of the stepper motor is not large enough, a larger locking torque is needed, or if the stepper motor loses its holding torque after a power outage, it can be considered to use a stepper motor with a brake.

How to achieve precise braking of three-phase AC brake motor?
In industrial production, motors are an indispensable source of power, but have you ever thought about how motors achieve rapid braking when equipment needs to be stopped urgently? Especially in scenarios such as cranes, conveyors, and automated production lines, the "emergency braking" ability of motors directly affects the safety and production efficiency of the equipment. Today, we will unveil the braking principle of common three-phase AC brake motors in industr

Guide you to understand the wiring details of explosion-proof motors
Explosion proof motor is a type of motor that can be used in flammable and explosive places without generating electrical sparks during operation. Explosion proof motors are mainly used in coal mines, oil and gas, petrochemicals, and chemical industries. In addition, it is widely used in sectors such as textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and medicine. Explosion proof motors, as the main power equipment, are usually used to drive pumps, fans, compressors, and other transmission machinery.
