Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Accompanying drawing discloses the structural representation of one preferred embodiment of this utility model without limitation, below with reference to attached
Figure explains the technical solution of the utility model.
Embodiment
120 type skewed slot non-brush permanent-magnet DC motor of a kind of small-power, as shown in figure 1, including stator (1) and rotor (4), institute
State rotor (4) to be arranged in stator (1)；Notches for wire (3) is offered on the stator (1)；The number of the notches for wire (3) is 24
Groove or 36 grooves, and the notches for wire (3) is uniformly distributed along the circumference of stator (1), and the central shaft of the notches for wire (3) and stator
Line is into inclination angle.
The notches for wire (3) is the waist-shaped hole of opening, and wire casing bending section (21) is provided with the opening of the waist-shaped hole.
Rotor tooth (41) is provided with the rotor (4), the rotor tooth (41) is circumferentially uniformly distributed along rotor.
On the rotor tooth (41), promising Ω types breach is set.
Fixing groove (43) is provided with the rotor tooth (41).
Through hole (42) is provided with the rotor tooth (41).
The present invention is 120 type skewed slot non-brush permanent-magnet DC motor rotor of small-power, constitutes complete electromagnetic system, the program
Wire casing bore is reduced, copper cash usage amount is reduced, tankful rate is improved, and stator slot quantity is defined as into 24 or 36 grooves, so as to subtract
Few excitation drift angle, reduces rotor deflection probability, reduces excitation transit time, increases magnetic pole stability, strengthens silicon steel sheet rigidity, together
When by testing repeatedly in a large number, determine that wire casing is inclined at an angle, successively stack that stator formation certain tilt angle makes to do
Inside during work(, cutting magnetic induction line is more steady, and running current is little, and delivery torque is bigger.When avoiding straight trough stator winding installation, amount of copper consuming
Greatly, tankful rate is low, inserting-coil process challenge, at the same can effectively solving straight trough stator current it is big, the shortcomings of rotator inertia is uneven.
Through my company's lot of experiments, the program improves 10% than common straight trough non-brush permanent-magnet DC motor stator torque, and efficiency increases
It is big by more than 5%, Considerable effect.Copper cash consumption is saved simultaneously, improves tankful rate, it is ensured that operation stability.
My company developed 120 type skewed slot non-brush permanent-magnet DC motor of novel electric tricycle small-power and turns surely in 2016
Son, is a whole set of motor electromagnetic system, and program wire casing is 24 groove of apsacline, in practice it has proved that, the stator scheme reduces original
Wire casing bore, reduces copper cash consumption, mitigates offline workload, and big with torque, noise is low, and copper loss is low, and efficiency height etc. is various excellent
Point, can meet higher use requirement in terms of non-brush permanent-magnet DC motor.
Reality of the present utility model is merely to illustrate above in conjunction with this utility model preferred embodiment described by accompanying drawing
Mode is applied, it is not as the restriction to aforementioned utility model purpose and claims content and scope, every according to this
The technical spirit of utility model still belongs to this practicality to any simple modification made for any of the above embodiments, equivalent variations and modification
New technique and rights protection category.
