Basic Introduction of Stepping Motor

As an actuator, stepper motor is one of the key products of mechanical and electrical integration,

widely used in a variety of automated control systems. With the development of the microelectronics and computer technology,

the demand of stepper motor is daily on the increase in applications over the national economy fields.

Stepper motor is an electric pulse that into the angular displacement of the actuator. Popular point is that when stepping the driver receives a pulse, it drives stepper motor to rotate along the direction set by a fixed angle (step angle).

You can control the angular displacement by controlling the number of pulses , so as to achieve accurate positioning purposes and can be controlled via a control pulse frequency motor rotation speed and Acceleration, so as to achieve the purpose of speed.

The aboved speed/torque curve is based on prostepper's test conditions. When the driving conditions change, the dynamic torque changes too.

The related current indicated in the specification is an effective value, please adjust the driver's current below the ralted current.


If you have motor pictures or drawings to show us, or you have detailed specs like voltage, speed, torque, motor size, working mode of the motor, needed lifetime and noise level etc, please do not hesitate to let us know, then we can recommend suitable motor per your request accordingly.

After confirmed the needed motor specs, we will quote and provide a proforma invoice for samples, once we get the payment, we will get a PASS from our account department to proceed samples accordingly.
