To achieve every time after startup of the motor on the 0 degrees towards, train of thought is to obtain the Angle of the motor current, then calculates the offset, let the motor rotation to 0 degrees, that how to obtain the motor current degree?

CodePudding user response:

Two solutions

1. When using the incremental encoder, using A phase B count, judge the position and location deviation correction, the absolute value Z phase power lost lost location data,

2. Use the absolute value encoder, to the absolute position of the motor to be direct, no lose when power supply drop location data,

CodePudding user response:

See you, this should be a steering motor rotation Angle of plus or minus 180 degrees, most use a absolute encoder is the best

CodePudding user response:

Index signal location will be dispatched directly to the upper part, electricity directly to zero
