Description
Technical field
The utility model is related to motor field more particularly to a kind of novel direct drive torque motors.
Background technology
Motor (Motor) is a kind of equipment converting electrical current into mechanical energy.It is to use the power on coil to generate rotation
Magnetic field simultaneously acts on rotor formation electro-magnetic motor force rotation torque.Motor is divided into dc motor and exchanges by using power supply difference
Motor, the motor in electric system are largely alternating current generators, can be synchronous motor either asynchronous machines.Motor
It is mainly made of stator and rotor, the direction of electrified wire movement under force in magnetic field has with current direction and magnetic induction line direction
It closes.Electric motor operation principle is effect of the magnetic field to electric current stress, makes motor rotation.
Direct driving motor is the abbreviation of direct drive motor, refers mainly to motor when driving load, is not required to fill by transmission
It sets (such as driving belt).Direct driving motor is suitable for all kinds of washing machines, and major benefit point includes mute, energy saving, steady, power
It is powerful.
Existing direct driving motor has that some are relatively difficult to overcome on the market：
1. the ripple power of existing direct-drive motor is bigger, cause motor that can not use relatively high to rotation smoothness requirements
The places such as occasion, such as grating imprinting/precision welding；
2. the space availability ratio of existing direct-drive motor is relatively low, the power that limited space generates is not big enough；
3. there are bigger defect, bad realization is accurately positioned in the case of high acceleration for the prior art；
It is difficult application in automation 4. under the prior art, the restricted lifetime of deep groove ball bearing causes electrical machinery life not grown.
Utility model content
In view of the above-mentioned deficiencies in the prior art, a kind of ripple power of the utility model offer is small, copper factor is high, the service life
Length simultaneously can realize pinpoint novel direct drive torque motor.
In order to realize that the purpose of utility model, the utility model use following technical solution：A kind of novel direct drive torque
Motor, including electric machine stand, stator, rotor magnet, bearing and encoder, it is characterised in that：The stator include stator card slot,
Stator silicon steel sheet and stator coil, the stator coil insertion stator card slot is interior and staggered floor arrangement, the stator are fixed on motor
Base inner, the stator are connected with rotor magnet by bearing, and the encoder is fixedly connected with rotor magnet by screw.
Preferably, the rotor magnet width is 2.3 times of stator coil width.
Preferably, the bearing is crossed roller bearing.
Preferably, the encoder is grating encoder.
The utility model has the beneficial effects that：By using the stator coil and rotor magnet of different in width, stator is avoided
Coil and rotor magnet generate bigger suction in the position of pole span, reduce ripple power, and motor rotation is smoother；Stator coil
By the way of staggered floor arrangement, the copper factor of stator card slot is improved, keeps motor power more powerful；Using crossed roller bearing, into
One step improves the service life of motor；The regular coding device on rotor magnet realizes the essence in motor high acceleration
Determine position.

Specific implementation mode
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
Embodiment 1
A kind of novel direct drive torque motor, including electric machine stand 1, stator 2, rotor magnet 3, bearing 4 and encoder 5,
It is characterized in that：The stator 2 includes stator card slot 7, stator silicon steel sheet 8 and stator coil 6, and the stator coil 6 is embedded in stator
In card slot 7 and staggered floor arrangement, the stator 2 are fixed on inside electric machine stand 1, and the stator 2 and rotor magnet 3 pass through bearing 4
Connection, the encoder 5 are fixedly connected with rotor magnet 3 by screw.
Further, 3 width of the rotor magnet is 2.3 times of 6 width of stator coil.
Further, the bearing 4 is crossed roller bearing.
Further, the encoder 5 is grating encoder.
Further, the stator coil 6 is applied in combination compact arranged mode, after thing is orthopedic is put into stator by hand
In card slot, stator coil 6 is arranged as staggered floor arrangement, and copper factor can reach 90%；The size of the stator silicon steel sheet 8 also passes through
Adjustment is crossed, the polarity non complete symmetry of stator silicon steel sheet 8 and stator coil 6 is made, reduces ripple power.
As can be seen from the above embodiments, the utility model ripple power is small, copper factor is high, long lifespan and can realize motor height
It is accurately positioned in fast rotation process.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
It is every simply to change or convert using made by the utility model description, it is relevant to be applied directly or indirectly in other
Technical field is equally included in the patent within the scope of the utility model.
