Example Embodiment

[0022] The motor drive device of the present invention integrates the strong and weak current parts into the drive board and the control board respectively, and installs the drive board and the control board in a rack, so that the entire motor drive device is not only compact in structure, but also can avoid strong current Interference with the weak current part.

[0023] Such as Figure 1-2 What is shown is a schematic diagram of an embodiment of the motor drive device of the present invention. In this embodiment, the motor driving device includes a main frame, a driving board 12, a control board 13, and a heat dissipation component. The driving board 12 is the strong current part of the device, and its input end is connected to the industrial frequency power supply, and the output end is connected to the power input end of the motor. The control board 13 is the weak current part of the device, and is used to control strong current processing (such as motor speed control, etc....

Abstract

The invention relates to a motor drive device which comprises a main frame, a drive plate, a control plate and a heat radiating assembly, wherein the main frame comprises a plate-shaped main body; the drive plate and the control plate are respectively fixed to the front of the plate-shaped main body and connected by an interface or a switching line; and the heat radiating assembly is fixed to theback of the plate-shaped main body and positioned under the drive plate. The invention also discloses the main frame in the motor drive device. The invention can prevent mutual interference by respectively integrating the strong current processing part and the weak current processing part into the drive plate and the control plate; and the whole device has compact structure and convenient installation and maintenance by reasonably laying the drive plate and the control plate to the same frame.

Description

technical field [0001] The invention relates to a driving device, in particular to a motor driving device and a main frame. Background technique [0002] Motor drive devices such as inverters are control devices that use the on-off function of power semiconductor devices to convert the input power frequency power into another frequency of electrical energy and output it to the motor. Usually, the motor control device includes a high-power processing part that processes the input power, and controls the high-power processing process or realizes other controls (such as processing call signals in the elevator controller or controlling car door switch detection, etc.) Weak current processing part. [0003] In the existing motor drive device, the heavy current processing control part and the heavy current processing part are usually placed on a first motherboard, and other control parts are placed on an independent second motherboard, and the first motherboard The board and the...
