What Is The Effect Of Temperature On Permanent Magnet DC Deceleration Motor

With the motor manufacturing industry from time to time to carry out, Permanent Magnet DC Deceleration Motor unit capacity increases from time to time, the operation of the unit volume loss is also generally increased, the temperature rise caused by the problem more prominent, the motor life and operation Reliability has brought serious impact.

The temperature increases, the Permanent Magnet DC Deceleration Motor is the winding insulation layer or the life of the winding is shortened, the magnetic density of the permanent magnet is reduced and the demagnetization of the permanent magnet, and the electrical precision is caused by the heat shrinkage, and the change of the electrical parameters caused by the temperature change is caused. Due to various reasons, subject to special operating environment constraints, direct measurement of the temperature of the motor parts will be a certain degree of difficulty. Thus, it is important to calculate the temperature of the motor for its design and optimization.

Temperature problem is a Permanent Magnet DC Deceleration Motor in the process of a problem can not be ignored, therefore, the operator work process not only to control the motor temperature, but also control the maintenance of this knowledge.

Brief introduction to the Permanent Magnet DC Deceleration Motor brush and brushless motor difference.

The main difference between them is that the field windings of Permanent Magnet DC Deceleration Motor are replaced by permanent magnets.

Permanent Magnet DC Deceleration Motor: is one or more permanent magnets to establish a magnetic field of the DC motor, its performance and constant excitation current of his excitation DC motor similar to the armature voltage can be changed by a convenient speed. Compared with the DC motor, it has the advantages of small volume, high efficiency, simple structure and low copper content. It is the main type of low power DC motor.

Permanent Magnet Brush DC Motor: Brush motor mounted on the stator with a fixed main pole and brush, the rotor is equipped with armature windings and commutator. DC power supply through the brush and commutator into the armature winding, resulting in armature current, armature current generated by the magnetic field interaction with the main magnetic field to produce electromagnetic torque, the motor rotating belt load. Due to the presence of brushes and commutators, the structure of the brush motor is complex, the reliability is poor, the fault is large, the maintenance workload is large, the life is short, and the spark is easy to produce electromagnetic interference.
