Technical field
The present invention relates to a kind of motor that is applicable to the application of low speed high torque plant equipment, relate in particular to a kind of low speed high torque fan sheet motor that is applicable to the major diameters such as ball mill, rotary kiln, mixer, the slow-speed of revolution, high torque (HT) class.
Background technology
The speed of service of low speed high torque manufacturing machine equipment such as ball mill, rotary kiln, mixer etc. is at 1 ~ 60rpm at present, basically all select synchronous speed to drag at interchange or the direct current machine of 600 ~ 1500rpm, because motor speed is high, torque is little, necessary supporting huge reductor, could with connect as production equipments such as ball mill, rotary kiln, mixers, make its work.But after motor carried out transmission by reduction gearing etc., not only the total system equipment volume increased, and weight increases, noise increases, moment of inertia increases, and Multi-stage transmission increases and installs and the maintenance difficult degree simultaneously, and has reduced operating efficiency.If can use slowspeed machine directly to drive these equipment, not only efficiency is high, and energy savings is easy to maintenance, and the while significantly reduces mounting cost, reduces the investment of other equipment.But existing motor all can not meet this requirement.
Summary of the invention
The purpose of this invention is to provide a kind of low speed high torque fan sheet motor, can be to the large-scale manufacturing machine direct-drive of low speed high torque.
The present invention adopts following technical proposals:
A kind of low speed high torque fan sheet motor, comprise the outer stator that arranges of rotor and rotor, described rotor periphery wall evenly is provided with a plurality of rectangular teeths, and described stator is fan-shaped, and the internal perisporium of fan-shaped stator is relatively set with rectangular teeth with rotor gear and the rectangular teeth width equates; Described fan-shaped stator is symmetrically installed with many to the magnetic pole winding, and each pole pair answers the number of rectangular teeth to equate.
Air gap distance between the magnetic pole of described stator and the magnetic pole of rotor is less than 1mm.
Two magnetic pole electrical current opposite directions of described every pair of magnetic pole winding.
Described rotor is the magnet steel gear.
Described stator is that magnetic links processes.
The external diameter girth of described fan-shaped stator is 1/8 ~ 1/10 of fan-shaped stator outer diameter place circumference.
On described fan-shaped stator, the logarithm of magnetic pole winding is two pairs or three pairs.
Described fan-shaped stator can be for a plurality of.
the present invention does rotor with large gear, 1/8 ~ 1/10 fan-shaped part of the outer perimeter of stator maximum gauge is as stator, and at the corresponding setting of the stator internal perisporium tooth identical with rotor tooth width size, three groups of magnetic pole windings are set again on fan-shaped stator, by controlling the electrical current size of every group of magnetic pole winding, the controlling torque size, change spinner velocity by energising direction and the direction change frequency of controlling every group of magnetic pole winding, realize low speed high torque, thereby do not need reducing gear just can directly drive the big machinery running, and then enhance productivity, energy savings, maintain easily, significantly reduce mounting cost, reduce the investment of miscellaneous equipment.
