Industrial ceiling fans have become standard equipment in many factory workshops. For industrial ceiling fans, the key is the motor part. Permanent magnet motors have become an important part of industrial ceiling fan design due to their high efficiency and energy saving characteristics. If you are a designer of permanent magnet motors for industrial ceiling fans, you need to understand the principles and applications of permanent magnet motors before designing.

A permanent magnet motor is a motor that uses magnets to rotate, with magnets embedded around the coils on the stator.

When AC or DC is input to the coil, a certain electromagnetic force will be generated, which will interact with the magnetic field to generate torque, thereby driving the motor to rotate.

Compared with traditional AC asynchronous motors, permanent magnet motors have higher efficiency and lower power consumption, so they are widely used in industrial ceiling fans and other fields.

In the design process of industrial ceiling fan permanent magnet motor, the main factors to be considered include speed, load, noise, etc. The following will introduce the application and design principles of permanent magnet motor in industrial ceiling fan design in combination with these factors.

Speed: For industrial ceiling fans, speed is one of the key parameters. Too high speed will increase the friction between the fan blades and the air, thus generating noise, and will also increase the power consumption of the motor. Too low speed will affect the air volume of the industrial ceiling fan.

Therefore, in the design of permanent magnet motors, it is necessary to adjust the coil parameters, such as the number of windings and length, according to actual needs to achieve a reasonable speed.

Load: The load that industrial ceiling fans need to bear is usually large, so the torque output needs to be considered when designing permanent magnet motors. Generally speaking, increasing the magnetic field strength of the permanent magnet material can increase the output torque of the motor; and increasing the number of turns of the coil can increase the rated load of the motor.

Therefore, when designing a permanent magnet motor, it is necessary to select a suitable motor model according to the actual load conditions and reasonably design the coil parameters.

Noise: Noise is a factor that requires special attention in the design of industrial ceiling fans. For permanent magnet motors, the noise mainly comes from the magnetic vibration in the permanent magnet material and coil and the noise of the mechanical structure.

In order to reduce noise, a shock-absorbing structure can be used, the permanent magnetic material and coil can be reasonably fixed and soundproofed, and noise compensation measures can be added.

When designing the permanent magnet motor for industrial ceiling fans, the focus should be on the speed, load and noise of the permanent magnet motor. These parameters must be carefully calculated and repeatedly confirmed to ensure that the industrial ceiling fan is safe and stable in actual use.
