Permanent Magnet Motor Overview

The permanent magnet synchronous motorcan integrally mount the motor on the crankshaft to form an integral direct drive system, that is, onecrankshaft is a drive unit, eliminating one gearbox. The permanent magnet brushless motor has excellent speed regulation performance similar to that of the DC motor, and overcomes the shortcomings caused by the commutating spark caused by the mechanical commutating device of the DC motor, and has low reliability, high operating efficiency, small size and light weight.

Permanent Magnet Synchronous Motor Features

Commercial permanent magnet ceiling fan motor adopts outer rotor structure, direct drive linkage and drive impeller rotation principle. 
Permanent magnet motor is built-in high insulation enamel coil, super magnetic steel body, high temperature resistance bearing, upper and lower end caps.

High Power Efficiency

PMSM has high power efficiency and power factor.

Low Noise

PMSM has low heat generation, so the motor cooling system has a simple structure, small volume and low noise.

Fully Enclosed Structure

No transmission gear wear and transmission gear noise, no lubrication.

High Reliability

PMSM allows large overload current, so the reliability is significantly improved.

Permanent magnet motor overview

  Duel King permanent magnet fan is with drive separation function. In the process of non-inductive drive, the ceiling fan will find the problem of finding the left and right. This is also the problem that the non-inductive drive can't solve at present.

Duel King team has verified the test machine several times and installed the drive separation mechanism to solve the problem. The buffer caused by the load makes it difficult to start.

In addition, it also has the function of separating the rotation inertia of the ceiling fan and the emergency stop deceleration in time to avoid the direct shutdown of the main power supply or the sudden power failure (equivalent to the sudden braking of the ceiling fan).

The inertia rotates against the impact of the motor and forms a self- generating condition, which damages the drive. The separation function is added to prevent this from happening, which makes the start and stop smoother.
