The synchronous reluctance motor 6 is applied to the drive of the roller body 1 of the mixing mill, and is mainly based on the "minimum reluctance principle" of the reluctance motor, that is, the magnetic flux is always closed along the path with minimum reluctance, and the reluctance torque generated by the D and Q axis inductance difference formed by the special salient pole structure design of the rotor drives the motor to rotate. The synchronous reluctance motor 6 is applied to the drive of the roller body 1 of the mixing mill, and mainly utilizes the reluctance motor The synchronous reluctance motor has the characteristics of high machine efficiency, high power factor and large speed regulation range. Ferrite is added inside the reluctance motor to make the starting current, working current and volume of the motor smaller than those of the asynchronous motor, and the power factor is higher than that of the ordinary asynchronous motor. The motor energy efficiency level can reach IE5 at a lower cost, and the power factor of the synchronous reluctance motor can reach 97%. Especially at low speed, the high efficiency range of the synchronous reluctance motor 6 is very wide. The application on the mixing mill can make full use of the high efficiency of the synchronous reluctance motor 6 at low speed, realize the energy-saving effect of the mixing mill, improve the motor drive efficiency, reduce power consumption, thereby reducing the electricity cost of the enterprise, and realize the smooth operation of the mixing mill at low speed, and improve the quality stability of rubber products.

When the motor needs energy, the electric energy of the supercapacitor energy storage system 71 is supplied to the motor after being inverted by the converter and the driver 73. The supercapacitor energy storage system 71 can store and release a large amount of electric energy in a short time, which can effectively meet the use of the synchronous reluctance motor 6, and at the same time can effectively buffer the fluctuation of electric energy and improve the dynamic performance of the motor.

[0042] The insulation box 81 can insulate the outer side of the synchronous reluctance motor 6 during use. The roller body 1 will generate a large amount of heat during actual use. The insulation box 81 can insulate the external heat to prevent high temperature from affecting the normal use of the synchronous reluctance motor 6. At the same time, the blower 84 can be started during use, so that the suction end of the blower 84 inhales wind through the connecting pipe 85, and then transmits the wind to the collecting bucket 83 through the output end. The wind can enter the insulation box 81 through the collecting bucket 83 and the connecting groove 82, dissipate the heat on the surface of the synchronous reluctance motor 6, and keep the temperature around the synchronous reluctance motor 6 normal at all times.

At the same time, the storage energy-saving component 7 cooperates with the thermal insulation and heat dissipation component 8 to effectively save energy and reduce consumption, thereby enhancing the use effect of the synchronous reluctance motor 6. It solves the problem that the current driving mode of the mixing mill adopts the driving mode of ordinary asynchronous motor or variable frequency motor, and the motor power used in the mixing mill is all in the medium and large power range.
