AC/DC three-phase permanent magnetic brushless DC motor controller

Abstract

The invention relates to an AC / DC three-phase permanent magnetic brushless DC motor controller which is formed by an upper shell, a base, a PCB and a remote receiving module, and the controller supports alternating current / direct current, wire control and wireless remote operation; A silicon carbide power tube is adopted, so that maximum operating temperature borne by the device can reach 600 DEG C, a cooling fin in the prior art is directly omitted, and miniaturization of the three-phase permanent magnetic brushless DC motor controller is possible; in addition, weak electric wires and strong electric wires of the controller are divided in structure, the strong electric portion comprises a wiring side and an AC input side of the permanent magnetic brushless DC motor, the weak electric portion comprises a wiring side of the control terminal, wiring identifies are simple and clear, and a wiring connector with a screw is adopted to complete the connection; the controller has advantages of strong anti-interference capability, simple mounting and use, wide application on several industrial sectors including home appliances, industrial robots, novel medical equipment, automation equipment and the like.

Description

Technical field [0001] The invention relates to an AC and DC dual-purpose three-phase permanent magnet brushless DC motor controller, which is mainly applied to many industrial sectors of household appliances, industrial robots, new medical equipment, and automation equipment. Background technique [0002] Article 17 of the "Energy Conservation Law of the People's Republic of China" expressly stipulates: "It is prohibited to produce, import, and sell energy-using products and equipment that are explicitly eliminated by the state or that do not meet the mandatory energy efficiency standards; it is prohibited to use energy-using equipment that is explicitly eliminated by the state. Production process." Article 18 stipulates, "The state implements energy efficiency label management for energy-consuming products with a wide range of applications and large energy consumption such as household appliances." Traditional Y series motors generally operate at rated points, and efficiency is...

AI Technical Summary

Problems solved by technology

[0004] 1. The shell of the permanent magnet brushless DC motor controller is basically an aluminum profile structure. At present, there is no controller similar to the PLC programmable controller structure to meet the needs of many applications.

[0005] 2. For the controller with aluminum profile structure, the wires basically come out from the end caps on both sides of the aluminum profile. There are many connecting wires, and there is a lack of necessary marks on the wire ends, which often leads to wiring errors, or the controller does not work due to poor connection. Necessary damage, complex installation process, not suitable for installation in general electric control cabinets or control boxes with guide rails

[0006] 2. The weak-current part and the strong-current part of the controller are mixed, and the electromagnetic interference is serious, resulting in poor reliability. Once damaged, maintenance is particularly difficult

[0007] 3. The controller lacks a unified energy management concept

[0008] 4. The controller only has wire control operation and does not support wireless remote control operation

[0009] 5. Without a heat sink, the VMOS power tube is particularly easy to burn out; if a heat sink is installed, the cost will remain high, and it is difficult to miniaturize the controller
