Permanent magnet DC geared motor main features

Jun 12, 2018

Permanent-magnet DC deceleration motors belong to DC motors. From the structural analysis, they can be regarded as a motor product that creates a magnetic field by one or several permanent magnets. The performance of a permanent magnet DC speed reduction motor is similar to that of a self-excited DC motor with a constant excitation current, and it can be easily adjusted by changing the armature voltage.


In comparison, permanent magnet DC speed reduction motors have many advantages. They are not only small in size, but also have high working efficiency. They are simple in structure design and save copper. They are the main types of low-power DC motors. At present, it has been widely used in the electronic and mechanical equipments of office, medical, home appliances, instrumentation and other industries as the driving and servo actuators.


Permanent magnet DC geared motor products main features introduced:

1, equipped with integrated gear reducer, load;

2, alloy steel gear, full bearing configuration, low noise.

3, the input shaft connection has a basic type (including a single input shaft and dual input shaft), with two kinds of motor flange.

4, the output shaft structure has a basic type (single output shaft, dual output shaft) and hollow output shaft two.

5, the direction of the output, input shaft input shaft in the direction of the next and in the; output axis up and down; input axial up and down.

6, in the work, you can choose 2 or 3 reducer to form a multi-stage reducer to obtain the required transmission ratio.


For the user, to ensure that the actual work is performed normally, it is necessary to reasonably select the power of the permanent magnet DC speed reduction motor. This is because the maximum power of the motor output is limited. If the motor power selection is too small, the motor overload will occur if the load exceeds the rated output power of the motor. When the motor is overloaded, there will be phenomena such as motor heating, vibration, speed drop, and abnormal sound.


If the problem is more serious, it may even cause permanent magnet DC geared motors to burn. And if the power is too large, it will cause economic waste. Therefore, it is very important to reasonably select the power of the permanent magnet DC speed reduction motor.
