1, what’s geared stepper motor nema 23?
The geared stepper motor nema 23 is an actuator that converts electrical pulses into angular displacement. Generally speaking: when the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed Angle (and step Angle) in the specified direction. You can control the Angle displacement by controlling the pulse number, so as to achieve the purpose of accurate positioning; At the same time, you can control the speed and acceleration of motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation
2. What kinds of stepper motors are divided into
Stepper motors are divided into three types: permanent magnet stepper motors, reactive stepper motors and hybrid stepper motors
Permanent magnet stepper motor is generally divided into two phases, small torque and volume, step Angle is generally 7.5 degrees or 15 degrees
Reaction stepper motor is generally divided into three phases, which can achieve large torque output, step Angle is generally 1.5 degrees, but the noise and vibration are very large. In Europe and the United States and other developed countries in the 1980s has been eliminated.
Hybrid stepper motors are a combination of the advantages of permanent magnet and reactive motors.
3. Under what circumstances is the off-line signal FREE of hybrid stepper motor driver generally used?
When the off-line signal FREE is low, the current output from the hybrid stepper motordriver to the motor is cut off, and the rotor of the motor is in a FREE state (off-line state). In some automation equipment, if the motor shaft is required to be turned directly (manually) when the driver is constantly energized, the FREE signal can be set low to make the motor offline for manual operation or adjustment. After manual completion, the FREE signal is swearhigh to continue automatic control.
