Product Details

Brief Introduction

 

The rated power of the rolling mill DC motor refers to the condition that the altitude does not exceed 1000 meters and the ambient air temperature does not exceed 40 ° C.

 

The armature circuit and excitation circuit of this series motor are suitable for thyristor power supply, and also suitable for DC generator.

 

The operating environment of this series of motors should not contain acidic, alkaline or other gases that have corrosive effects on insulation.

 

The motor can be installed in harsh environmental conditions, but the correct cooling method and protection level must be selected to protect the normal operation of the motor.

 

If the motor is used in the ship and hot and humid areas, and there is smoke and humidity in the working environment, it should be separately agreed.

 

When the motor is powered by a static rectifier power supply, the pulse number of the rectifier should not be less than 6, and the peak ripple factor of the power supply should not exceed 10% at the rated base speed, rated voltage and rated load current.
