YCT Series Electromagnetic Speed Regulation Three-Phase Asynchronous Motor

YCT series adjustable-speed induction motor by electromagnetic clutch is one of the derived series from Y series three phase asynchronous motors, they are composed of driving motors, electromagnetic slip coupling and controller. YCT motors are usually used under a constant torque load and are particularly suitable for the use under the load with a decreasing torque such as the centrifugal pump and fan. Main applications of the YCT including assembly lines, transfer equipments, plastic injecting machines, printing machines, pumps, fans, wire calendars, drawing machines etc.

YCT series electromagnetic speed motor usually with the JD,TXZ,CTK series controller composed of a set of exchange has a the velocimetry negative feedback system stepless drive , a wide speed smooth stepless speed regulation,it is with in China,s unified design new Electromagnetic Motor has the advantages of high efficiency, low noise, vibration, high reliability, and aesthetic appearance. And in line with national international Electrotechnical Commission(IEC) standards.

The speed of the YCT series motors can be adjusted continuously and steplessly within the specified adjustable speed range with an output of rated torque. When the loading torque is changed during the running of the motor, the exciting current of the coupling can be regulated automatically by the speed negative feedback system of the controller, so as to keep the speed free of any variation basically.

YCT/YCTL Electromagnetic Speed Regulation Motor Principle

The stepless speed regulation is achieved by electromagnetic clutch, it has two rotating parts, cylinder armature and claw poles, no mechanical connections between them, the motor pull the armature rotating with the rotor, and when there is direct current passing through the exciting coil, space-alternating magnetic field will be induced in the air-gap, the armature will cut the magnetic lines and induce electrical current, the inductive current will produce a magnetic field too, the effect of the two magnetic fields will produce torque. The rotating direction of the output shaft is the same as the pulling motor, and under certain load its speed depends on the value of the exciting current, higher current causes a higher speed, no current no torque output.

YCT Series Electromagnetic Speed Regulation Three-Phase Asynchronous Motor Main features:

A. High-precision of speed regulation.

(1)It was eliminated the periodic instability of the speed-adjustable motor by changing the axial magnet of the motor to be the constant magnetic claw plate radial magnet three-phase frequency generator.

(2)The controller adopted the speed controller to achieve the purpose of automatic stabilizers speed manner, thereby increasing the rate of change of speed of the motor speed. There are precise controller and normal controller, Normal speed controller enables the rate of change within the rated speed range less than 2.5%, the precise controller enables precision speed change rate less than 1%. The maximum motor voltage is 90VDC.
