Lab 10a Overmodulation
1. Because our products require normal output torque in the environment of 0-50 C. In the environment of 50 C, Rs is required to take a larger value to make the motor output torque, but at this time in the environment of 0 C, the motor will start over-current problem, how to solve it?
2. Because our products require normal output torque in the environment of 0-50 C. In the environment of 0 C, Rs is required to take a smaller value to make the motor output torque. At this time, the motor can also start normally, but at this time in the environment of 50 C, the motor has no output torque. How to solve this problem?
3. Because our products require normal output torque in the environment of 0-50 C, is there any scheme that can be compatible with both high and low temperature environments? Resistance Rs on-line identification value is not accurate and can not meet the high and low temperature performance. Is there any other suitable scheme?
