Promotion and use of ultra-efficient motors, ultra-efficient motors, has become an important part of energy strategy developed countries. Efficiency ultra-efficient motor efficiency motors off than average increase of 2 percentage points. American and European countries in the universal application of high-efficiency motors, the end of the century and have developed a super high-efficiency motor standard. The United States, Canada and the EU to impose ultra-efficient motors are standard. My Government in 2008 to one of the countries included in the motor system energy ten energy saving projects, again in 2010 to promote the application of high-efficiency motors included projects that benefit. In order to meet the changing needs of the international market, energy efficient motors, to meet domestic and export needs, we designed YE3 series (IP55) ultra-efficient three-phase induction motor (frame size 80 to 355). Speed ??motor is by changing the motor series, voltage, current, frequency and other methods to change the motor speed to the motor to achieve a higher performance of the motor. The main types of products are DC motor, frequency conversion motor, electromagnetic speed motor. AC YCT series three-phase asynchronous motor speed motor, electromagnetic slip clutch, speed generator, electrical control devices consisting of constant-torque motor, slip clutch solenoid by SCR control can be achieved even stepless speed, widely used in constant torque variable speed on a variety of equipment. YCT speed motor performance close to the recent series of international advanced level, is based on JZT series electromagnetic speed motor, the design and manufacture of the latest products. YCT series speed motor has a cylindrical armature and claw pole no mechanical coupling two rotating parts, armature driven by the drive motor for synchronous rotation, energized, generates a magnetic field in the working air gap, high efficiency motor, the armature cutting EMF magnetic force lines and the formation of eddy currents and magnetic field interaction of the magnetic field, electromagnetic force, the claw-shaped magnetic pole and the armature to maintain a certain speed difference for the same direction of rotation, so that the output torque, steering and drive motor output shaft direction consistent, change the size of the excitation current, you can easily adjust the output speed.
