1. What is the starting current and starting torque of the motor when running with an inverter?
The inverter is used for operation. With the acceleration of the motor, the frequency and voltage are increased accordingly. The starting current is limited to less than 150% of the rated current (125% ~ 200% depending on the model). When starting directly with power frequency power, the starting current is 6 to 7 times the rated current, therefore, mechanical and electrical shock will occur. The inverter drive can start smoothly (starting time becomes longer). The starting current is 1.2 ~ 1.5 times of the rated current, and the starting torque is 70% ~ 120% of the rated torque. For the inverter with automatic torque enhancement function, the starting torque is more than 100%, and it can be started with full load.
2. What does V / f mode mean?
When the frequency decreases, the voltage V also decreases proportionally. This question has been explained in answer 4. The proportional relationship between V and f is predetermined in consideration of the characteristics of the motor. Usually, there are several characteristics stored in the storage device (ROM) of the controller, which can be selected with a switch or a dial.
