What is a Variable Frequency Drive? (Part 1)

You can divide the world of electronic motor drives into two categories AC and DC. A motor drive controls the speed, torque, direction and resulting horsepower of a motor. A DC drive typically controls a shunt wound DC motor, which has separate armature and field circuits. AC drives control AC induction motors, and-like their DC counterparts-control speed, torque, and horsepower.

What is the relationship between angular velocity and rpm

Mar 27, 2015Let's say the wheel is revolving n times per minute. So, the rpm of the wheel is n. In a single revolution, a point on the wheel rotates an angle=2*pi. So, the total angle a point on the wheel is rotating per minute = n*2*pi. The angular velocity (Omega) is a measure of how fast a wheel is rotating.

The carrier frequencies are usually between 800 Hz to 15 kHz, and currents at these high frequencies will cause R losses. While the high frequency currents are relatively nominal, the loss relates to the current's square power. And the carrier frequency, even at its square root, can be somewhat effective because of its basic high value.
