1. Power supply not connected: If the power supply is not connected or has poor contact, it will cause the motor to not rotate. At this time, electricians should check the switch, fuse, various contacts, and wiring heads to gradually identify the fault and carry out maintenance;2. When starting, the fuse of the fuse is blown, causing it to not tu...

1. Single phase faultThis situation occurs when any phase of the power supply voltage is lost. This is because the normal operation of a three-phase induction motor requires a three-phase voltage source. Due to this malfunction, the motor may burn out or generate heat.2. Reverse phase sequence faultWhen any phase of the three-phase power supply i...

The winding problem of a DC reduction motor is a complex problem, and the winding is an important component of the reduction motor. Once a fault occurs, serious problems can occur. However, we need to explain some characteristics and characteristics of the winding in the reduction motor (or gear reducer) clearly.1. The basic data of the winding s...

Zeroing is a big issue in servo control. There are a variety of system requirements for zeroing, different zeroing methods supported by each manufacturer's motion controller or driver, and a variety of feedback types for servo motors, resulting in a variety of zeroing methods. In addition, the description of key terms related to zero return varies ...

The linear motor has a compact structure, low power consumption, fast operating speed, and high acceleration. By directly driving the load, high-precision position positioning control from high speed to low speed can be achieved. Linear motors have a low failure rate, are maintenance free, and have a long service life. If the environment is not han...

Steps for calibrating permanent magnet synchronous motors:1. Determining the coordinates of the calibration starting point usually involves single component adjustment of the d-axis and q-axis components of the current, obtaining the gradient vectors of the d-axis and q-axis of torque variation with the current.2. Calculate the test current based ...

In the no-load experiment of asynchronous motors, a three-phase voltage regulator is used to supply power, causing the stator terminal voltage to gradually decrease from (1.1-1.3) Un, and the no-load current to gradually decrease until there is a significant change in the motor speed and a significant increase in no-load current. Why does a decreas...

The DC brushless motor eliminates the carbon brush and slip ring structure, reduces friction losses, and significantly improves the efficiency of the motor. At the same time, the motor itself has no excitation loss, further improving the comprehensive power saving rate, which can reach 20% to 60%. This efficiency makes DC brushless motors perform w...

Sometimes, the deceleration motor may not rotate during use. So, let's summarize how to determine the quality of the three-phase asynchronous motor coil and what instruments should be used for inspection:1. A megohmmeter can be used to measure the insulation resistance between motor phases and phase to ground, and should not be less than 0.5 megoh...
