To some, motor speed control is somewhat of a mystical science, a science that causes motors and machines to sometimes operate in unexpected ways. Over 30 years ago, AC drives were considered "new ...

Voltage source inverter VFDs are ideal for dynamic applications, where there is the need to achieve fast changes in motor torque and speed. Pulse width modulation (PWM) type VFD features a ...

Understand how to specify the proper AC or DC motor for a machine design. Integrate the motor to a machine, based on analysis of motor equations for voltage, current, torque and speed. Implement the ...
