Motors that require insulated bearings are mainly used in special working environments where it is necessary to prevent current from being conducted to the bearings and reduce the impact of sparks or electrostatic discharge on the bearings. Here are some common motor types that require insulated bearings:
High-voltage motor: The insulated bearing of the high-voltage motor is used to isolate the high-voltage circuit inside the motor from the bearing support part to prevent current from being conducted to the bearing and avoid damage to the bearing by current.
Frequency changing motor: The frequency changing motor is an adjustable speed motor, and its main feature is that the output frequency can be adjusted. Frequency changing motors usually require the use of insulated bearings to prevent current from being conducted to the bearings during frequency changes and protect the normal operation of the bearings.
Live parts motor: There may be live parts in the internal structure of some special motors, such as brushes, collector rings, etc. These live parts will generate current and may cause damage to bearings. Insulated bearings are required to prevent current conduction to the bearings. High-temperature motors:
High-temperature motors usually require the use of special insulated bearings to ensure the normal operation of the bearings in high-temperature environments. Insulated bearings can provide stable support and axial guidance in high temperature environments and reduce the impact of temperature on the bearings.
In short, motors that require insulated bearings are mainly used in special working environments that need to prevent current from being conducted to the bearings and reduce the impact of sparks or electrostatic discharge on the bearings.
