Direction and recommendation of the First, energy efficient motors is the inevitable direction of the motor industry. Vigorously promote the policy level and a huge market growth space for motor energy saving materials, energy-saving motors, etc. bring a lot of investment opportunities; second, Linfen motors, energy efficient motors will drive the rapid development of the industry chain. Energy efficient motors upstream industry chain, including copper, aluminum, silicon, magnetic materials and other raw materials suppliers and downstream is the channel vendors, application vendors efficient motors; the third, local governments should intensify the development of industrial planning, strengthen the construction of industrial facilities, vibration motors, and support and encourage corporate mergers and acquisitions, to promote the formation of industrial agglomeration. Electromagnetic Induction Motor structure and working principle of electromagnetic induction motor speed control is composed of ordinary squirrel-cage induction motor, electromagnetic slip clutch and electrical control equipment of three parts. Asynchronous motor as a prime mover, drive clutch when it rotates together with the rotation of the armature, cone motors, electrical control devices to provide slip clutch field coil excitation current devices. This introduces the electromagnetic slip clutch, Figure 2-19 is the structure diagram. It includes an armature, the pole and the excitation coil of three parts. The armature is made of cast steel cylindrical structure, which is connected to the shaft squirrel-cage induction motor, commonly known as the active part; claw-shaped structure made of poles, mounted on the load shaft, commonly known as the driven part. The active part and the driven part of the machine without any contact. When the magnetic field generated by the excitation coil current, the claw-shaped structure will form a lot of poles. At this point, if the armature is dragged squirrel cage induction motor rotates, then it will be cutting the magnetic field interact to produce torque, so the driven part of the pole will be followed by the active part of the armature rotates together, the speed of the former than the latter, Because only when the armature and the magnetic field there is relative motion of the armature to cut magnetic lines. Principle pole with the armature rotates along with the general principle of induction motor rotor rotating magnetic field of the stator winding movement is no different, except that: asynchronous motor rotating magnetic field produced by the stator windings of a three-phase alternating current and electromagnetic slip clutch by a magnetic field in the excitation coil produces a DC current, and since the rotation of the armature only play the role of a rotating magnetic field.
