This method produces reduced torque ripple
resulting in smoother motor performance and quieter operation.
Pulse width modulation technique is an important role for drive performance in respect to, switching losses, harmonics and torque ripple
from an induction motor.
Many of these applications require minimum torque ripple
, and reduced vibration and acoustic noise that urge the development of different control strategies [1-4].
In high-speed brushless DC (BLDC) motors and permanent magnet synchronous motors (PMSM) the sensor s high accuracy enables better execution of the commutation scheme, resulting in higher torque and efficiency, lower torque ripple
and smoother operation.
Sealed ball bearings and reduced torque ripple
from skewed magetization also ensure a smooth operation at any speed.
He covers the mathematical modeling and characteristics analysis of brushless direct-current motors, simulating motor drives, speed control for motor drives, analyzing and reducing torque ripple
, sensorless control of motor drives, and realization of drives.
