The power supply mode of the micro DC motor is direct current, so it can be powered by a battery. The use of permanent magnets in the micro motor is to prolong the battery life, save the excitation coil, and reduce the volume. Today, we will introduce the type of permanent magnet used.
Now, most micro motor manufacturers use neodymium magnets, and a few motor manufacturers also use samarium cobalt magnets and ordinary ferrite magnets. The shapes are mainly ring-shaped and arc-shaped. The following is an introduction to the use of magnets for micro motors.
For permanent magnet ferrite, because of its good high temperature resistance (250 ° C) and low price, it is necessary to consider whether the magnetic field strength can meet the requirements.
The NdFeB strong magnet has a temperature resistance of about 200 °C, which fully meets the working temperature requirements of the micro motor. Its price is cheaper than samarium cobalt, and the price is in the middle.
The above is the introduction of magnets used in micro motors. Our company can provide various multi-pole neodymium magnets, neodymium arc magnets, and injection-molded ferrite magnets. You are welcome to provide drawings to inquire about prices and samples.
