You will find permanent magnet motors in any number of appliances in your daily life, from toothbrushes to mobility solutions; but what exactly are they and what are their advantages? In this article, we will focus on PMDC motors, which are the most common type of permanent magnet motor. As trusted manufacturers of motors for 75 years, Parvalux PMDC motors are specified by manufacturers in a huge range of industries.
Like an AC motor, a permanent magnet motor uses electromagnetism to generate torque. PMDC motors have permanent magnets in the stator that provide the magnetic field needed to make it function. This is an alternative to traditional brushed or brushless DC motor, where the magnetic field is created in the stator windings..
As the magnets are fixed in a permanent magnet motor, you cannot control the magnetic field strength externally. This means that you are likely to find PMDC motors in applications where the speed doesn’t need to be controlled. This being said, control can be achieved by controlling armature voltage, so they are not necessarily excluded from use in industries where speed and torque need to vary.
They are an excellent choice for products in the leisure and healthcare industries because PMDC motors offer an impressive output and are high performance, despite being generally smaller than other motors.
Depending on whether you are using it as a motor-only or in combination with a gearbox, any Parvalux permanent magnet DC motor can be built to fit your power requirements.
