This paper proposes a torque ripple reduction for brushless DC (BLDC) permanent magnetic (PM) motor drive based on the DC-link voltage pulse amplitude modulation (PAM). The proposed method improves ...

In the last section, we have the motor driver circuit. Each motor driver circuit consists of SI2302 N-Channel MOSFET along with a flyback diode and pulldown resistor. There are 4 such circuits, for ...

This paper presents a soft-start circuit using the pulse width-modulation (PWM) method. The motor is controlled by the dc chopper associated with a low-cost PWM chip TL494. The design criteria are ...
