1. Additional torque
The torque that occurs on the motor shaft under additional voltage, extra load is called the extra torque of the motor.
2. Starting torque
The torque generated by the motor at the moment when a voltage is applied to the motor in the aborted condition is called the starting torque. The starting torque characterizes the starting ability of the motor, which is related to the starting method (such as step-down starting, communication servo motor frequency conversion speed regulation starting, winding motor series resistance starting, etc.).
For the directly started squirrel cage motor, the starting torque is generally 0.8-2.2 times of the additional torque. In general, the starting torque should be more than 1.25 times the additional torque, and the corresponding starting current should be 5-6 times the additional current.
Regarding the large DC servo motor, the starting torque is particularly large, so the starting current is also very large, so the large Guangzhou DC servo motor should not be started directly, and the voltage should be reduced. The exception is small Shenzhen DC servo motors and permanent magnet servo motors.
3. Large torque
*High torque is the point where the torque stabilization zone of the motor is bordered by the unstable zone. If the load torque is greater than the maximum torque, the output torque of the motor will become smaller and enter the stalled rotor condition. At this moment, the current will be very high, and the motor will be burned out as a result.
4. Stalled torque
After the Japan servo motor enters the stalled rotation condition, the speed is zero, and the torque that the motor can output is the stalled torque.
5. The relationship between torque under different conditions
* The large torque is greater than the extra torque, but the stalled torque of the asynchronous motor may be greater than the * large torque or less than the additional torque, the former is due to the different motor parameters of the stalled rotor condition and the * large torque condition, and the latter is planned and confirmed according to the actual working conditions.
After the above introduction, when we use the motor, we should reasonably adjust the motor torque according to the operation status at that time.
Shenzhen Servo Huakexing is the general agent of Fuji servo motor, which can provide Fuji servo motor, Japan servo drive, Fuji servo motor price consultation, Fuji servo motor selection and Japan Fuji servo models stock supply.
