Abstract

The utility model relates to a brushless motor of a built-in intelligent power module controller. The motor consists of two parts, namely, a drive motor and a motor driven control system, wherein the drive motor comprises a front end cap, a rear end cap, a stator core, a winding coil and a rotor part; and the motor driven control system comprises a motor driven controller, and an intelligent power module is mounted on the motor driven controller. The brushless motor has the advantages that by adopting the intelligent power module to replace the design of a driver chip and a plurality of power MOS (Metal Oxide Semiconductor) tubes used in the prior art, the size and physical dimensions of the whole motor are also correspondingly smaller and compacter, and the application range is wider; and through simplifying the structure of the motor and the motor driven control system, the production cost and the process flow are reduced, the reliability of the motor system is increased, control and fast switching between the driver and the outside are achieved, and the motor system is kept in highly efficient and highly reliable operation.

Description

The brushless electric machine of built-in intelligence power model controller

[technical field] the utility model relates to permanent magnetic brushless and makes the field, relates to particularly a kind of brushless electric machine of built-in intelligence power model controller.

[background technology] non-brush permanent-magnet DC motor has the advantages such as speed adjustable range is wide, overload capacity is strong, reliable, efficient is high, noise is little, mechanical property is strong, volume is little, is widely used in civilian, industry and military field.The drive circuit of existing built-in controller the control system for non-brush direct currunt electromotors, what use is to drive chip and a plurality of power MOS pipe, have following problem: one, power MOS pipe first will be fixedly mounted on the aluminium radiator fin of processing processing, again aluminium radiator fin is fixed on by screw, heat-conducting glue and carries out the embedding processing on motor case, this processing mode has caused very burden can for inspection and the repairing in later stage, go wrong whole control board is scrapped, and manufacturing process is comparatively complicated and strict, and manufacturing cost is high.Two, between electronic component, the difference of performance parameter own can affect the consistency of driving control system for electric machine, the increase of electronic devices and components number not only can extend production hour, affect production efficiency, also can cause controller frequently to break down, normally move thereby affect electric system.

The technical problem that [summary of the invention] the utility model solves is to provide a kind of brushless electric machine of built-in intelligence power model controller, this motor has that integrated level is high, reliability is high, compact conformation, insulating properties is high, range of safety operation is wide, thermal conductivity is good and the advantage such as low electromagnetic interference, to solve the deficiency in the above-mentioned background technology.The technical problem that the utility model solves realizes by the following technical solutions:

The brushless electric machine of built-in intelligence power model controller, formed by drive motors and driving control system for electric machine two parts, its two part is connected and composed at motor internal by electronics lead-out wire separately, it is characterized in that, described drive motors comprises front end housing, rear end cap, stator core, winding coil and rotor part, and winding coil and stator core are installed in front end housing; Described driving control system for electric machine comprises motor drive controller, and Intelligent Power Module is installed on motor drive controller, and motor drive controller is arranged in rear end cap by the rear end cap screens; Be provided with the insulating heat-conductive plate between motor drive controller and rear end cap; Screening arrangement is arranged between front end housing and rear end cap by clamp nut and trip bolt.

Described motor drive controller is provided with motor phase line cap, power end lead-out wire and speed governing port lead-out wire.

The utility model has the advantages that: 1, with the driving chip that uses in the alternative prior art of an Intelligent Power Module and the design of a plurality of power MOS pipe or IGBT electronic devices and components, volume and the overall dimension of control system have been reduced, the volume of whole motor and overall dimension are also corresponding less, compacter, and range of application is more extensive.2, built-in 6 the fast quick-recovery power MOS pipes of Intelligent Power Module, 3 half-bridge high pressure gate driver circuits; built-in under-voltage protection cross conduction protection circuit; independently bear dc terminal so that be used for the detection of inverter current for built-in 3; adopted the design of low electromagnetic interference effectively to be reduced in when using the electromagnetic interference of electronic equipment on every side, the insulation rank is up to 1500Vmms/1min.3, by simplifying the structure of motor and driving control system for electric machine, save production cost and technological process, improved the reliability of electric system, realize control and high-speed transitions between driving and outside, kept electric system high efficiency, highly reliable operation.4, the screening arrangement that arranges can improve the antijamming capability of driving control system.
