PMDC motor design is based on permanent magnets in place of a wound field to enable a lighter, more compact and efficient motor with wider speed range.
AC shaded-pole motors are widely used in small household appliances such as electric fans, hair dryers and vacuum cleaners because of their simple structure, low manufacturing cost and low running noise.
Brushless motor with copper coil has low induction value and quick response of current to voltage fluctuation. The moment of inertia of the rotor is small, and the response speed of torque and current is equal, so the acceleration of the rotor can reach twice that of the traditional motor.
A Shaded Pole motor is an AC single phase induction motor. The auxiliary winding, which is composed of a copper ring, is called a shading coil. The current in this coil delay the phase of magnetic flux in that part of the pole in order to provide a rotating magnetic field. The direction of rotation is from the unshaded side to the shaded ring.
Made of quality materials, lightweight and in mini size. These ultra-compact small DC motors are designed to deliver superb speed-to-torque performance with lower joule heating.
Micro dc motor has the characteristics of remarkable energy saving, electricity saving, low noise, low voltage starting, strong vibration force and high efficiency, delicate appearance and light weight, which can be easily installed.
