In this post, we want to talk about Permanent Magnet Synchronous Motors and Capacitor Start Induction Motor. After introducing and reviewing each, we will examine the difference between motor and engine.
Permanent Magnet Synchronous Motors
First, we define the synchronous motor. A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles.
The Permanent Magnet Synchronous Motor (PMSM) is an AC synchronous motor whose field excitation is provided by permanent magnets. The permanent magnet synchronous motors are very efficient, brushless, very fast, safe, and give a high dynamic performance. Due to their advantages, permanent synchronous motors have many applications and find use in several fields.
Permanent Magnet Synchronous Motor (PMSM) is brushless and has very high reliability and efficiency. Due to its permanent magnet rotor, it also has a high torque with a small frame size and no rotor current.
Capacitor Start Induction Motor
A motor capacitor, such as a start capacitor or run capacitor (including a dual run capacitor)is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field.
A Capacitor Start Motors is a single phase Induction Motor that employs a capacitor in the auxiliary winding circuit to produce a greater phase difference between the current in the main and the auxiliary windings. The capacitor start motor has a cage rotor and has two windings on the stator. They are known as the main winding and the auxiliary or the starting winding.
Differences Between Motor and Engine
By Wikipedia definition:An engine or motor is a machine designed to convert one form of energy into mechanical energy.
But what is the difference between motor and engine?
Motor” is originated in the Classical Latin movere, “to move.” It first mentioned the propulsive force, and later, to the person or system that moved something or caused the movement.
“Engine” is from the Latin root: mental powers, character, intellect, talent, or cleverness. In its journey through the French language and into English, the term came to mean contrivance, ingenuity, and trick or malice. “
