Abstract
A split type permanent magnet synchronous motor with embedded position sensor, the rotor noumenon is spliced by a permanent magnet, the space between a stator and a rotor has no shaft bearing to connect, and the stator and the rotor joint use the shaft bearing with the automobile motor and the gear box, the position sensor is embedded in the inner part of the motor, to match the motor driver to joint use.
Description
Affiliated technical field
The utility model belongs to energy field, cooperates motor driver, converts electric energy to mechanical energy.
Background technology
At present, known permanent magnet synchronous motor adopts traditional electric machine structure more,, consists of one by stator, rotor and end cap etc. that is, and position transducer is positioned at the outside of motor, makes the structure of motor not compact, and axial dimension is big.And the motor on the mixed power electric car requires axially and radial dimension is little, and the power of motor is big, and the utility model is a kind ofly can be coupled as one, compact conformation, volume is little, energy density is big, control precision is high motor with its gearbox.
Summary of the invention
The prior motor structure is not compact in order to overcome, size is big, can not satisfy electric automobile special operation condition defective, the utility model provides a kind of permanent magnet synchronous motor of split type embedded position transducer and its load to organically combine, compact conformation is fit to the electric automobile work condition requirement.
The technical scheme that its technical problem that solves the utility model adopts is: no bearing connects between its stator and the rotor, but and automobile engine and the shared bearing of gearbox, simultaneously required exact position transducer is embedded in motor internal, thereby has reached compact conformation, purpose that axial dimension is little.
The beneficial effects of the utility model are, compact conformation, and volume is little, and is in light weight, and cost is low, and energy density is big, satisfies the special operation condition requirement of electric automobile.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structure general assembly drawing of the present utility model, wherein, 1---motor case, 2---stator, 3---winding, 4---magnet steel, 5---rotor, 6---position transducer.
Embodiment
In the accompanying drawing, motor case (1) is by the surface engagement location, with the transformer Bolt Connection of electric automobile; Rotor (5) and transmission main shaft seam rigid attachment; The bonding magnet steel of rotor (5) outer surface (4).Connect three-phase alternating current when stator (2), produce rotating magnetic field, rotating magnetic field drags rotor (5) rotation, and rotor (5) is by the transmission main shaft output mechanical energy.Control signal is exported by position transducer (6).
Claims (2)
1. the permanent magnet synchronous motor of a split type embedded position transducer, be made up of stator, rotor, magnet steel is arranged on the rotor, it is characterized in that: motor stator, rotor are split type, the required exact position of synchronous machine transducer is embedded in motor internal, motor and other load direct connections.
2. the permanent magnet synchronous motor of split type embedded position transducer according to claim 1, it is characterized in that: synchronous motor stator and rotor do not have the shared bearing of bearing and engine and gearbox.
