Stepper motor is a special motor, which is specially used for precise control of position and speed. Its working principle is to convert DC power into time-sharing power supply, and multi-phase sequence control current. Work, the drive device is a time-sharing power supply to the stepper motor, multi-phase sequence controller. The following small series of stepper motor manufacturers will introduce the differences between 42, 57, and 86 stepper motors.

Differences between 42, 57, and 86 stepper motors:

42 Stepper motor refers to the stepper motor installed on the base, and the upper limit of its output torque is 0.5NM;

57 stepper motor refers to a stepper motor with a size of 57mm installed, and the upper limit of its output torque is 3.0NM;

86 stepper motor refers to a stepper motor with a size of 86mm, which is a high-precision motor.

Parameters of 42 series two-phase stepping motor:

Step accuracy 5%

The temperature is 80℃Max.

Normal temperature 20℃~50℃.

The isolation resistance is 100MΩMin500VDC.

Voltage resistance is 500 volts.

Z maximum radial runout 0.02mm (450g load)

Z maximum axial runout 0.08mm (450g load)

Parameters of 57 series two-phase stepping motor:

The isolation resistance is 100MΩMin500VDC.

Voltage resistance is 500 volts.

Z maximum radial runout 0.02mm (450g load)

Z maximum axial runout 0.08mm (450g load)

Parameters of 86 series two-phase stepping motor:

Step accuracy 5%

The temperature is 80℃Max.

Normal temperature 20℃~50℃.

The isolation resistance is 100MΩMin500VDC.

Voltage resistance is 500 volts.

Z maximum radial runout 0.02mm (450g load)

Z maximum axial runout 0.08mm (450g load)

The above is the introduction of the difference between the 42, 57, and 86 stepper motors. The biggest feature of the stepper motor is its "digitization". The stepper motor controls each pulse signal and is driven by it. It is driven by a fixed angle. If a series of pulse stepping motor is received, it can run continuously for a corresponding distance. And by controlling the pulse frequency, the motor speed can be directly controlled. Because the stepping motor is easy to learn, low cost (related to servo), and the motor and driver are not easily damaged, it is very suitable for microcomputer and single-chip control. In recent years, it has been widely used in control equipment in various industries.
