Load Torque Observer for Minimising Torque Ripple in PMSM

, 2004
Permanent magnet synchronous motors generate parasitic torque pulsations owing to distortion of the stator flux linkage distribution and variable magnetic reluctance at the stator slots. The consequences are speed oscillations which deteriorate the performance drive in various applications.

Reduction of Torque Ripple in Induction Motor Drives Using an AdvancedHybrid PWM Technique

, 2010
A voltage source inverter-fed induction motor produces a pulsating torque due to application of nonsinusoidal voltages. Torque pulsation is strongly influenced by the pulsewidth modulation (PWM) method employed.

A non-unity torque sharing function for torque ripple minimization of switched reluctance generators

, 2013
This paper presents a new torque ripple minimization technique for a Switched Reluctance Generator (SRG). Although the SRG has many advantageous characteristics as a generator, it has not been widely employed in the industry.

Torque Ripple Sensor and Mitigation Mechanism

, 2006
A torque ripple sensor and method for torque ripple sensing and/or mitigation. A piezoelectric sensor is positioned relative to a motor so that torque fluctuations due to torque ripple of the motor are transmitted to the sensor, resulting in strain of a ...
