3HAC025338-002/06C ABB Robot Adapter

The induced voltage of motor winding is higher than that of power frequency power supply. 5SHY3545L0020 can not expose insulation defects during power frequency power supply, because it is not resistant to the impact of induced voltage under high-frequency carrier wave, the voltage breakdown between turns or phases of the winding occurs. As we all know, the inverter has perfect protection circuit. With the up converter, the motor will not burn? The answer must be no, the protection circuit of the inverter is not. Compared with power frequency power supply, motor is easier to burn with up converter. The interphase, turn to turn short circuit or grounding of the motor winding causes a sudden short circuit of the motor winding, which may blow up the module or burn the motor during operation.
Under the influence of high-speed switching of semiconductor switch, the output voltage waveform of frequency converter will make the voltage superimposed on the running voltage of the motor, and will generate pulse over-voltage on the motor terminal. The peak value is about twice of the DC part voltage, posing a threat to the motor insulation to the ground. The 5SHY3545L0020 insulation to the ground will accelerate its aging under repeated high-voltage impacts.

In fact, motor faults are not caused by the motor itself. Most of them are caused by the nonstandard commissioning of frequency converter or the use of non frequency converter motor as a frequency converter motor. The main reasons are as follows:
1. Use ordinary motor as frequency conversion motor
Because the ordinary motor cooling fan is connected with the shaft, when the frequency converter is used for speed regulation, the speed of 5SHY3545L0020 is unstable, which can not reach the rated speed of the motor, and the cooling fan can not play a normal role, causing poor heat dissipation of the motor; In addition, the ordinary motor is not designed according to the frequency conversion requirements, which makes the motor hot or burned.
2. Frequency conversion motor and frequency converter are directly connected for use without debugging
Vector control and V/F curve control are the two most commonly used methods for motor control by frequency converter. For each control method of 5SHY3545L0020, the motor type (synchronous, asynchronous, with or without encoder), motor rated power, rated voltage, rated current, speed or number of poles, rated frequency, operating frequency, acceleration and deceleration time of motor starting and stopping, protection method of motor controlled by frequency converter and protection proportion coefficient shall be firstly determined The carrier frequency is well set, and none is necessary. After these parameters are set, choose vector control or V/F control. When vector control is selected, the motor shall pair with the inverter for dynamic self-learning with no load or static self-learning with load, and the motor after self-learning can play the role of vector control with the inverter; When V/F control is selected, self-learning is not required, and power on operation is directly conducted after parameters are adjusted.
