Abstract:

Purpose. The goal is to synthesize a simple way to suppress the cogging torque in the transverse flux motor (TFM), which is a special type of the synchronous motor with permanent magnet. This TFM is meant to be used in direct drive of the C-Press with ServoDirekt-technology.

Methodology. To justify the opportunity of the cogging torque compensation via a special harmonic component of stator current.

Findings. The simple modified way of the cogging torque compensation for transverse flux motor and the synchronous motor with permanent magnet has been proposed, which minimizes ripples of the torque in broad spectrum of the operation speeds.

Originality. The presented research shows that compensation of the cogging torque depends on rotation speed of the motor. Therefore the phase delay and the amplitude ratio factor between current reference and the reproduced electromagnetic torque must be taken into account.

Practical value. Using this control law in drive with TFM or another synchronous motor with permanent magnet it is possible to improve the quality of the forming technology.
