Description
Technical field
The utility model relates to a kind of permanent magnet synchronous motors, belong to motor technology and field of energy-saving technology.
Background technique
In existing asynchronous machine, motor rotor is all squirrel-cage cast-aluminum rotor either Wound-rotor type copper rotor, cast aluminium
For rotor because the resistance of aluminium is big, the electric efficiency being made into is low, and loss is big.The superiority and inferiority of casting aluminum rotor directly affects motor quality and enterprise
Benefit, and the defects of broken strip of the centrifugal aluminum casting rotor in casting process, slice and crackle motor quality can be caused it is very big
It influences.Wound-rotor type copper rotor processing technology is complicated, and motor manufacturing is at high cost.
Permanent magnet synchronous motor is a kind of energy-saving efficient motor, has vast potential for future development.But permanent magnet synchronous motor opens
Streaming current is very big, needs to start with frequency converter.The utility model provides a kind of permanent magnet synchronous motor, and asynchronous open may be implemented
Dynamic, synchronous operation not start with frequency converter.
Utility model content
The utility model provides a kind of permanent magnet synchronous motor, by casing, end cap, bearing, stator winding, stator core,
Rotor and connection box set are at casing, end cap, bearing, stator winding, stator core and the terminal box of permanent magnet synchronous motor and common
Asynchronous machine is identical, and rotor is made of red copper ring, permanent magnet, magnetic guiding loop and motor shaft, and magnetic guiding loop is mounted on motor shaft, red copper
Ring is mounted on the excircle of magnetic guiding loop, and permanent magnet is also mounted on the excircle of magnetic guiding loop, and red copper ring is replaced with permanent magnet conclusion of the business
Step-by-step arrangement has air gap, the bearing and former and later two end caps that rotor passes through both ends between red copper ring and permanent magnet and stator inner circle
It is connected, former and later two end caps are fixed on casing both ends.Magnetic guiding loop on rotor by mild steel or silicon steel sheet group at.Red copper ring can be with
Using being fixed on magnetic guiding loop after copper plate edge rolling.The processing is simple, and permanent magnet uses the structure of surface-mount type.
It is asynchronous starting, electricity when starting the beneficial effects of the utility model are: being permanent magnet synchronous motor when the motor operation
Machine manufactures simple process, and electric efficiency is high, and energy-saving effect is good.

Specific embodiment
Further illustrate specific embodiment of the present utility model with reference to the accompanying drawing:
Attached drawing 1 is the schematic diagram of the specific embodiment of the utility model permanent magnet synchronous motor, and permanent magnet synchronous motor is determined
Subdivision is made of casing (8), stator core (7), stator winding (4), terminal box (5): stator core (7) is fixed on casing
(8) in, in the punching slot of stator core (7), terminal box (5) is mounted on outside casing stator winding (4).
The rotor portion of permanent magnet synchronous motor is by motor shaft (2), magnetic guiding loop (6), red copper ring (9) and permanent magnet (15) group
At magnetic guiding loop (6) is on motor shaft (2), and red copper ring (9) is mounted on the excircle of magnetic guiding loop (6), permanent magnet (15)
It is mounted on the excircle of magnetic guiding loop (6), red copper ring (9) and permanent magnet (15) strike a bargain and replace step-by-step arrangement, red copper ring (9) and permanent magnetism
There are air gap (13) between body (15) and stator core (7) inner circle.
Both ends, bearing outer ring is in the bearing hole of drive end bearing bracket (3) and rear end cap (12), drive end bearing bracket (3) and rear end cap
(12) both ends of casing (8) are mounted in, fan blade (11) is mounted in the other end of motor shaft outlet side, and fan housing (14) turns in casing (8)
Rear end cap (12) side is protected fan blade (11).Magnetic guiding loop (6) on rotor by mild steel or silicon steel sheet group at.
Rotating excitation field is generated after electrical power, red copper ring (9) cutting magnetic line and generate an opposite magnetic field, two magnetic
Field interactions, rotor can start, and after starting, rotor revolving speed is synchronous with rotating excitation field revolving speed, red copper ring (9)
No longer cutting magnetic line, motor synchronous operation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on are all contained in the utility model
Within protection scope.
