Often, a simple control scheme using a microprocessor can allow manufacturers to use lower starting torque compressors without the use of a hard start kit to operate their ice machines. Before the ...

In fact, both capacitors are wired in series with the start winding and in parallel with the run winding. The run capacitor limits the current that will pass through the start winding when the motor ...

Some motors can start under load, and some can’t. Where a motor is coupled to the load without an intervening clutch system on the load end, assume the motor cannot start under load unless you verify ...

Electric motors, both ac and dc types, come in many shapes and sizes. Some are standardized versions for general-purpose applications. Others are intended for specific tasks. In any case, motors ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

Oversizing often happens when engineers try to match the inertia between the load and the motor rotor, so that they can tune the drive’s velocity, torque or position loop relatively tightly to meet ...

Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system. These inrush currents can cause sags ...

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...
