Embodiment Construction

[0012] Examples of the present invention figure 1 As shown, the integrated motor I is a motor including three completely overlapping stator units (1a, 1b, 1c). The three stator units are all connected in a Y-shape and share a rotor 2, forming a logic motor consisting of three Composed of integrated motors. The stator unit in each logic motor has a set of corresponding independent connection terminals, which are respectively connected to a control unit (3a, 3b, 3c), that is, each control unit controls a complete three-phase stator winding. Using the Controller Area Network 4 ("CAN"-Controller Area Network for short), the three control units are connected together to form a triple synchronous array controller II to control the integrated motor I. It is also possible to use other on-site low-level equipment control network systems to connect the above-mentioned control units, and the formed synchronous array controller has the same effect.

Abstract

The invention relates to a synchronization array control device suitable for integrated electrical motor containing a plurality of control units. Each control unit includes a microprocessor unit which is connected with a display module, keyboard entry unit, detecting, driving and protection unit, network linkage unit and power module. All the control units are integrated with the control network through the on site low level apparatus, The control units are independent on the output end, forming a control array with network arrangement, and thus a synchronization array control device. The operation dependability and safety for the motor control and operation are improved effectively.

Description

technical field [0001] The invention relates to a motor control device, in particular to a network coordinated synchronous array controller suitable for integrated motors. Background technique [0002] Most of the controllers used in the existing three-phase asynchronous motors, permanent magnet synchronous motors and other motors are composed of microcomputer systems, control circuits and corresponding power modules such as GTO, IGBT, IGCT or IPM. Generally speaking, each controller is responsible for controlling the operation of a motor. For high-power motors, due to the need to use high-power GTO, IGBT, IGCT or IPM power modules that match the power of the motor, the cost of the controller is very high, and because these high-power modules are currently available only in a few Western countries Manufactured, and is a high-tech product that is restricted for export. Therefore, for our country, the control of high-power motors is still a weak link and is restricted by for...
