DC Motor Drive Protection Scheme

A DC motor refers to a rotating electrical machine that can convert DC electrical energy into mechanical energy or mechanical energy into DC electrical energy.

Features

●Good starting and speed regulation performance, wide and smooth speed regulation range,

●Strong overload capability and less affected by electromagnetic interference;

●DC motor has good starting characteristics and speed regulation characteristics;

Fig.1

Features

●The torque of the DC motor is relatively large;

●Maintenance is relatively cheap;

●DC motor is more energy-saving and environmentally friendly than AC;

Fig.2

New materials for NdFeB magnet motors are widely used, and brushless motor BLDC technology has been vigorously developed. Yint Electronics conducts in-depth research to improve the stability of products save energy and reduce consumption for Yint Electronics planet. Provide Yint Electronics complete electromagnetic compatibility solution for brushless motor electronic control!

Table.1

Note: The selection of MOV and NTC needs to be selected according to the motor power and usage scenario.
* For M7, it is important to choose devices with excellent heat dissipation and excellent VF performance.

Table.2

Table.4

Note: If the DC bus voltage is not too high, it can be completed by a single TVS. If the voltage is too high, it can be completed by multiple low-voltage IVSs connected in series. However, care should be taken to suppress the series parasitic inductance to avoid overcharging when the active clamping voltage is too high.
