field weakening造句

Analysis of step field weakening process under the characteristic control

In the field weakening region, the torque capacity decreases with the increasing frequency, torque output capacity depends largely on the field-weakening control strategy.

The proposed algorithm guarantees producing the maximum torque over the entire field weakening region and ensures the torque and speed-rising capability under imperfect field orientation c.

These traction motors with Class H insulation are permanently connected in matic field weakening is provided and multiple-unit control is fitted.

The torque characteristics, power characteristic and field weakening characteristic of the SPM motor have been analyzed in details by the phasor method.
