1, what is the stepper driver half-current hold function? Half-current drive is a commonly used control method in stepper motor control. The realization of half-current drive requires the stepper driver to have the ability to select half-current drive. Once the half-current drive mode is turned on, the drive current of the stepper motor will be reduced to half of the set current value, and even if there is no movement of the motor, the driver will still provide enough current to keep the motor in position. This can reduce the heat loss of the motor, reduce noise, and improve the accuracy and stability of the motor.   However, under some working conditions, stepper motors need to work in full-current drive mode, otherwise it will affect the efficiency and accuracy. At this time, it is necessary to have a stepper driver with automatic switching half-current/full-current mode. Stepper driver automatic half-current function to realize the principle is mainly through the detection of ... Continue reading →

Stepper motor noise is unavoidable, but you can control its use conditions and control methods to relatively reduce the noise. There are two main aspects of motor noise generation: inherent noise and resonance.   Inherent noise: the motor in the process of rotation, the mechanical structure of the mutual contact generated. It is impossible to eliminate, but through some methods can reduce the noise to a certain extent. Adjust the load or drive current to avoid the noise caused by the motor out of step (jump step) due to the load is too large (too small); the use of subdivided drive, so that the motor current changes as close as possible to the cosine curve changes to reduce the output torque fluctuations due to changes in current, resulting in some noise;   Noise caused by resonance: As there is a certain resonance region of the motor, using it in this speed range will cause the motor to resonate and generate noise. Therefore, for the noise caused by resonance, the ... Continue reading →

Gear reducer, also called gearbox, is mainly used to convert the high-speed and low-torque direct output of motors (except servo motors) into low-speed and high-torque output. Therefore, the connection between the motor and the gear reducer is an important link in achieving force and power transmission, and is also the key to ensuring the normal operation of the entire system. There are many options for connecting the motor and gear reducer. Common methods include flange connection, bearing connection and direct connection. 1. Flange connection is a commonly used method of connecting motors and gear reducers. It connects the output shaft of the motor to the input shaft of the gear reducer through a flange. The flange is usually made of metal material and has fixing bolt holes and holes that match the motor output shaft. Reliable connection can be achieved by bolting the flange to the corresponding holes of the motor output shaft and gear reducer input shaft. 2. Bearing connection is ... Continue reading →

It is not the same as stepper motor speed regulation, which works on the basis of rotating a step angle each time a signal is received. Instead, stepper motor speed regulation uses a technique called frequency speed regulation, in which the motor's speed is adjusted by varying the pulse signal's frequency. The speed of the motor cannot be altered by adjusting the pulse signal voltage.)，the brushless motor (bldc motor​) has three speed adjustment methods:   1. Voltage speed regulation: Generally, a brushless motor is matched with a driver. By changing the output voltage of the driver, the input voltage of the brushless motor can be controlled to adjust the motor speed.   2. PWM speed regulation: PWM speed regulation uses pulse width modulation to modulate the constant DC power supply voltage into a pulse voltage sequence with a constant frequency and variable width, so that the average output voltage can be changed to adjust the motor speed. The speed can be adjusted ... Continue reading →
