Description
Technical field
The present invention relates to not have axle is outer-rotor structure permasyn morot location torque proving installation, belongs to Motor Control Field.
Background technology
In permanent magnetism class (brushless or have brush) motor, even when the motor winding is opened a way, motor also presents a kind of periodically pulsing moment, this moment is caused by teeth groove factor or magnetic saturation factor, and always attempt rotor is positioned at a certain position, this moment is exactly usually said location torque.
Location torque is that the motor magnetic resistance is inhomogeneous to be caused because the existence of stator teeth groove makes, and it is the intrinsic phenomenon of permagnetic synchronous motor.The location torque of permasyn morot be motor not the energising just exist and the moment relevant with the position of state, from source analysis, comprise magnetic hysteresis location torque and magnetic resistance location torque.Location torque directly produces fluctuation moment in Direct Driving System, location torque will exert an adverse impact to motor properties, for example, the low-speed performance of speed control system and the hi-Fix of position control system be had tangible influence.Therefore, accurately measure the torque motor location torque characteristic of analyzing permasyn morot is had crucial effects.
There is the not high problem of precision in the existing technology of measuring the permagnetic synchronous motor location torque, and complex structure.
Summary of the invention
