Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

Motor control centers (MCCs) were first introduced in 1937 as a way to conserve wall and/or floor space in industrial facilities. Before 1960, wall-mounted motor starters were used even if only a few ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

Designers of motion control applications are under pressure to optimize performance and efficiency while keeping component count and space to an absolute minimum. The ideal situation is sensorless ...

Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...
