What is a Synchronous Reluctance Motor?


Ⅰ、Motor Type


Synchronous Reluctance Motor


1.Introduction

Nowadays, with technological innovation and industry requirements, motors are developing rapidly. Synchronous Reluctance Motors are increasingly gaining popularity across various industries due to their high efficiency and remarkable reliability. These motors operate on a principle that does not rely on permanent magnets, unlike traditional motors. The absence of permanent magnets not only makes them more cost-effective but also significantly more environmentally friendly, as they reduce the need for rare earth materials. Because of this, they are becoming a preferred choice for applications where sustainability and cost savings are crucial.


2.Principle
◆ a. Reluctance Torque:

Synchronous reluctance motors operate on the principle of reluctance torque. It exploits the natural tendency of magnetic flux to flow through the path of least magnetic resistance (reluctance).

◆ b. Rotor Design:

The rotor of a SynRM is usually constructed of salient poles (also known as flux barriers) made of ferromagnetic material. These poles are designed to minimize the magnetic resistance of the flux path.

◆ c. Stator Windings:

The stator has three-phase windings that produce a rotating magnetic field when three-phase alternating current is passed through it.

◆ d. Torque Generation:

When the stator windings produce a rotating magnetic field, the rotor poles align with this field due to their reluctance properties. This alignment produces torque, which drives the motor.

1. Introduction

Permanent Magnet Assisted Synchronous Reluctance Motors, on the other hand, represent a sophisticated hybrid technology that combines the intrinsic benefits of both synchronous reluctance motors and permanent magnet motors. These advanced motors incorporate permanent magnets to further enhance their performance characteristics. The inclusion of permanent magnets results in motors that are even more efficient and powerful, providing an ideal solution for high-performance applications where superior efficiency and power are required. This blend of technologies ensures that users can achieve optimal performance while still enjoying the economic and environmental benefits associated with synchronous reluctance motors.


2. Principle
◆ a. Combination of Reluctance and Permanent Magnet Torque:

PMa-SynRM combines the principles of reluctance torque and permanent magnet torque.

◆ b. Rotor Design:

Similar to the SynRM, the rotor of PMa-SynRM has salient poles to facilitate reluctance torque. Additionally, it includes embedded permanent magnets in the rotor poles.

◆ c. Operation:

When the stator windings create a rotating magnetic field, both the reluctance torque (due to the rotor's shape) and the additional torque from the permanent magnets contribute to the overall motor torque.

◆ d. Enhanced Performance:

The permanent magnets assist in increasing torque density, improving power factor, and extending the speed range compared to traditional SynRM motors.

◆ e. Efficiency:

PMa-SynRM motors typically exhibit higher efficiency and power density compared to SynRM motors, especially at lower speeds and under partial load conditions.
