10 commonly used professional terms for permanent magnet motors

There are many types of permanent magnet motors, and everyone needs to distinguish them. Permanent magnet DC motor is one type of permanent magnet motor, and there are many different professional terms for permanent magnet motor, and each professional term has a different meaning. The following are the 10 commonly used majors of permanent magnet motors that the editor will introduce. I hope you can understand the terminology after reading it!

The 10 commonly used professional terms for permanent magnet motors are as follows:

1. Electrical appliances: electrical equipment that performs on-off switching of power grids or power circuits.

2. Contacts: The contacts in electrical equipment that connect or break circuits are called contacts or contacts.

3. Fuse and its function: A fuse is an electrical appliance used in permanent magnet motor circuits to protect against severe overload or short circuit.

4. Inching control: Press the button once, and the motor of the permanent magnet motor will rotate once, and then release the button, and the motor will stop. This kind of control is called inching control.

5. Sequence control: The control implemented in the order according to production needs is called sequence control.

6. Contactor and its function: The contactor in the permanent magnet motor is an automatic control electrical appliance used to connect or cut off the AC and DC main circuits and control circuits.

7. Under-voltage protection: The protection measures taken when the line voltage is lower than the rated value are called under-voltage protection.

8. Inherent mechanical characteristics of the permanent magnet DC motor: the operating voltage and excitation flux of the motor are rated values, and the mechanical characteristics are when there is no additional series resistance in the armature loop.

9. Artificial mechanical characteristics of permanent magnet DC motor: Artificially change the parameters of the motor, such as armature voltage, armature loop resistance and field flux, and the corresponding mechanical characteristics are artificial mechanical characteristics.

10. Self-locking: The effect of relying on the normally open auxiliary contact of the contactor to keep the coil energized is called self-locking (also known as self-protection).
