JDS series digital display electromagnetic speed-adjusting motor controller(populary called as slide-differential motor controller) is used to control the speed of the alternative current electromagnetic speed-adjusting motor, and to realize the stepless speed adjusting with constant rotation.
JSD series controller samples the revolving speed signal from speed measuring generator, which is displayed by digital meter or indicatted by the pointer of simulated meter after treatment. It can indicate the actual speed of motor accurately, in spite of that the user needn't to check the meter for different magnitude of the sensitivity of the speed-measuring generator. This series of controller provided with the functions of smoothly soft start without sudden leap and overshoot at motor starting and protection for rotation blocking of the electromagnetic clutch. Due to adopting PI control, it has the merits of high accuracy of control, smooth operating, good speed adjusting performace, etc. and realizing the bidirectional manual/automatic translation without disturbance.
By forming a complete set of JDST synchronous operator and JDSD automatic digital display electromagnetic speed-adjusting motor controller( or JDSC automatic electromagnetic speed-adjusting motor controller with pointer), can constitute conveniently the synchronous control system with more one electromagnetic speed-adjusting motors(slide-differentinal motors).
