The choice of miniature DC deceleration motor material

Micro DC deceleration motors are very widely used miniature motors. They are mainly used for products that require high speed and require large torque outputs, such as electronic intelligent locks, micro printers, electric fixtures, etc. The micro -deceleration DC motors need to be used. The choice of micro -DC deceleration motor is also very important, and it mainly needs to be considered from various aspects.

There are two types of magnetic fields in the iron core magnetic circuit of the micro -DC deceleration motor: constant magnetic field and interlaced variable magnetic field, so the nature of the magnetic field needs to be considered. The iron core is a component of the micro -DC deceleration motor carrying magnetic flux and a fixed rotor winding. It is usually stacked by silicon steel sheets. For iron core rotors working in constant magnetic fields, electricity can be used. Magnetic guidance rate. For the iron core rotor working in the interlaced magnetic field, the appropriate silicon steel sheet can be used to ensure the magnetic guidance rate and saturated magnetic secret.

The directionality and uniformity of the magnetic guidance rate of the iron core to the iron core of the micro -DC deceleration motor, the hot -rolled silicon steel sheet is divided into two types: orientation and no direction. For the same -sex requirements of magnetic field distribution, if it is a large DC deceleration motor (greater than 900 mm in diameter), you need to use orientation silicon steel sheets (silicon steel: the main materials are iron and silicon iron alloy, with a silicon content of about 3%~ 5%) Essence

Considering the height of the magnetic tight of the micro -DC deceleration motor iron movement, the iron core can be divided into two types: high and low. For iron cores with high work magnetic tight, silicon steel sheets or electrician pure iron should be selected. Considering the impact of the impact of the core loss on the structural process on the loss of the micro -DC deceleration motor, pay attention to the thickness selection of the silicon steel sheet. Increased damage, but the number of stackers is small. Micro DC deceleration motors can be relaxed properly on the iron loss value of iron core materials.
