The geared motor is a digital actuator with good performance. In the point control of the CNC system, the reduction motor can be used as the driving motor. The performance of a geared motor usually decreases after reaching 700 rpm. Sometimes the speed of the motor does not increase, or the motor freezes or loses steps. Obviously, if we encounter this situation, how to solve it? The editor below will introduce to you what happens when the reduction motor gets stuck.
First, change the parameters of the motor; secondly, the power supply voltage of the reduction motor can be increased so that the effective current magnetic field during commutation increases due to the high voltage at high speed.
If there is no isolation between the AC power supply and the DC bus of the stepper driver (such as a transformer), do not ground the non-isolated port of the DC bus or the ground wire of the E-isolated signal, which may cause equipment damage and personal injury. Because it is an ordinary AC power supply, the voltage is not grounded, and there may be high voltage between the DC bus ground and the ground.
1. In most high-voltage stepper drive systems, all common grounds and grounds are connected together at the signal end. Ground loops created by various grounding methods are susceptible to noise and flow at different reference points.
2. In order to keep the command reference voltage constant, the signal ground of the reduction motor driver should be connected to the signal ground of the controller. It also connects to the ground of the external power supply, which can affect the operation of the controller and geared motor driver.
3. It is difficult to ground the shielding layer. There are several methods. A correct shield ground is at a reference potential point within its circuit. This depends on whether the noise source and receiver are both grounded or floating. Make sure the shield is grounded at the same point to prevent ground current from flowing through the shield.
