d、 Holding torque:
It refers to the torque at which the stator locks the rotor when the stepper motor is powered on but not rotating. It is one
of the most important parameters of stepper motors, and the torque of stepper motors is usually close to the holding
torque at low speeds. Due to the continuous attenuation of the output torque of a stepper motor with increasing speed,
and the variation of output power with increasing speed, maintaining torque has become one of the most important parameters
for measuring a stepper motor. For example, when people refer to a 2N. m stepper motor, unless otherwise specified, it means a
stepper motor that maintains a torque of 2N. m.
Common faults and maintenance of stepper motor drivers
Given that many friends are not familiar with how to handle faults in stepper motor drivers, today the editor has listed some common
causes and solutions for stepper motor driver failures.
1. Stepper driver malfunction
Reason for malfunction: Electrostatic discharge (poor working environment).
Troubleshooting method: First, connect the PE in the electrical cabinet to the ground. If there is still a fault, the driver module is damaged and needs to be replaced.
2. Motor stalling at high speed
Reason for malfunction: Design issues with the transmission system.
Exclusion method: If the high-speed jog does not cause blockage when the feed rate is 85%, use the line acceleration feature;
Reduce the maximum feed rate; Replace the fire torque stepper motor.
