Brushless Direct Current Motor, also known as an electronic commutation motor (ECM or EC motor) or synchronous DC motor, is a type of synchronous motor that uses a direct current (DC) power source. A brushless DC motor is essentially a permanent magnet synchronous motor that uses a DC power input and is converted into a three-phase AC power supply ...

1. The connecting bolts are prone to twisting and breaking. For a screw conveyor composed of several screws, the connecting bolts at the head section bear the torque of the fully loaded motor, while the torque borne by the subsequent screw sections and connecting bolts decreases. Therefore, the connecting bolts at the head section are easily twiste...

A stepper motor is an actuator that converts electrical pulses into angular displacement. When the driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction (known as the stepper angle) and rotate at a fixed angle. The angular displacement can be controlled by controlling the number of pulses to achiev...

1、 Selection of stepper motor torque. The holding torque of a stepper motor is similar to the power of a traditional motor. Of course, there are also essential differences. The physical structure of a stepper motor is completely different from that of an AC/DC motor, and the output power of the motor is variable. Usually, the type of motor is selec...
