It can be made higher.The precision of winding is critically important for the motor of axial magnetic field, because it is related to the size of motor gas-gap, into
And influence the performance of motor.
Since single-phase PMSM has the characteristics that driver circuit is simple, it is widely used on miniature PMSM.Using axial magnetic field
Single-phase PMSM, winding space be with maximum outreach be 180 ° of electrical angles centralized configuration arranged.This winding
Utilization rate is fine in terms of the linkage of rotor field, and winding coefficient is also just higher.These are very heavy to the performance for improving motor
It wants.But after using this winding, when using multi-layer PCB, in order to connect the PCB for being located at different level, it is necessary in phase
With connecting hole connection positioned at the winding in different PCB layer faces between the winding layers of pass.Have to use when designing and producing PCB
" buried via hole " connects the winding in different level with the mode of " blind hole ".Because winding is complicated, to buried via hole and blind hole
Requirement it is also complicated.This can make the cost of PCB very high.If using via, every layer of coiling must avoid the position of via.
This can make the shape of winding become unreasonable, to influence the performance of motor.

The electric current of winding is controlled and is commutated.One specific question of this motor is that there is the points that multiple torques are zero for it.
When motor operation, these zero torque points can be passed through using machinery inertial.But motor is when starting, if turned
Son is located at the position of these torque zeros, then motor can not normally start.When design of electrical motor, it is necessary on electromagnetic structure
Try to avoid when starting rotor to be located at the position of torque zero.
Motor in axial magnetic field, rotor must be clamped down on axially, to avoid rotor in axial movement, or even be detached from
Motor.The method that machinery may be used is clamped down on.It can also be clamped down on using magnetic force.The structure of the latter is simple, especially suitable
For thin electric motor.But how to be realized in the electromagnetic structure using motor, then need to consider many factors.
5) it is located at the locating plate in the same PCB layer face of electronic device, quadrature-axis reluctance can be utilized to be less than the effect of direct axis reluctance,
So that rotor when freely stopping, is parked in the bigger position of detent torque, to reinforce the startability of motor.Depending on
Magnetic force caused by effect between bit slice and the magnetic field of magnet steel can also play the role of rotor axial clamp down on.
