What Causes The High Temperature Of High-power Brushless Dc Motors?

Table of Contents

DC Brushless Motor

Running Time Is Too Long

High-power Brushless DC motors are not suitable for long-term continuous operation, and use in this case may cause the temperature to rise. Although motors at high temperatures can still be used, for safety reasons, machine action requirements need to be re-evaluated to determine whether the motor type needs to be changed.

Action Frequency And Cycle

Excessively high operating frequency may cause the temperature of the Brushless DC motor to rise. It is recommended to reduce the operating frequency to reduce the motor load.

Adjust The Operating Current

In the case of sufficient torque, reducing the operating current of the Brushless DC motor can effectively reduce the temperature. If larger currents must be used, it is recommended to consider upgrading the Brushless DC motor grade.

Adjust The Stop Current

While maintaining sufficient torque, reducing the stop current can effectively reduce the temperature. If larger stopping torque is required, it is recommended to upgrade the Brushless DC motor grade.

Ambient Temperature

Excessive ambient temperature will also cause the Brushless DC motor temperature to rise. It is recommended to take heat dissipation measures, such as installing a cooling panel or cooling fan.

Wiring Error

Confirm whether the wiring at the motor end is correct. Wrong phase wiring may cause the Brushless DC motor to run unstable and jitter, and may also cause excessive temperature rise.

In summary

In order to ensure the stability, integrity and lifespan of high-power Brushless DC motors during use, it is necessary to eliminate the causes of high temperature problems one by one.
