If you’ve ever wondered at the operating of a big machine, like an elevator or conveyer belt, then you’ve probably heard of a 4 pole synchronous motor. These units are essential to many industries as they help everything operate with ease and efficiency. Today we are going to learn what FENG YIN 4 pole ac motor, how they work, and when to use them.
A 4 pole syncronous motor is an electric motor that uses magnets to produce rotation. As opposed to induction motors, synchronous motors runs at a fixed speed at a given number of poles. A 4 Pole Synchronous Motor rotates at a speed proportional to its supply frequency which makes it ideal for applications requiring precise speed control.

C3W4 The 4 pole synchronous motor is a very elegant, effective simple design. It consists of two essential entities: a stator and a rotor. The rotor, the part that moves, links to the machine, and the stator, the one that does not, holds the motor’s wires. As electricity flows through the wires in the stator, a magnetic field is created that collides with the rotor’s magnetic field and causes the rotor to turn.

There are a lot of reasons why 4 pole synchronous motors are used in industries, the top reason is its efficiency. These FENG YIN shaded pole synchronous motor require a steady pace to maintain productive work, so it won’t be using energy as much as other engines. This saves electricity and is more friendly on the environment.

Why 4 pole synchronous motors are high efficiency and high power? The high efficiency and power of 4 pole synchronous motors stem from the design and operation. These FENG YIN shaded pole asynchronous motor can run smoothly and consistently via constant speeds, which is significant for jobs that require precision. And they work in unison, which means they can generate more power at lower speeds — great for tough jobs.
