The permanent magnets commonly used in our company are neodymium-boron-iron materials, and their maximum operating temperature is different depending on the grades used. For example, N38EH, the maximum working temperature of its material can reach 200℃, but we redesign it according to 180℃ as the limit.
Motor noise varies greatly depending on the specifications of the motor. Permanent magnet motors running below 200 rpm usually have a noise below 80dab. The noise of permanent magnet motors with operating speeds above 750 rpm is generally around 85dab.
The motor basically has no operating costs and only requires routine maintenance. If the environment is poor, the motor with the external fan and the attachments of the external fan need to be cleaned regularly to avoid additional power loss.
