AC speed controller JD6A

three-phaseslip-ring motormotion control

JD6 series variable-speed motor controller is new type production,is applicable for speed control of electromagetic governor motor(slip motor),to achieve constant torque stepless speed. This series production has the following advantages of convenient and easy operation,balance start and operation of controlled motor,high-accurency control,digital diplay and othre multi-functions. Normal operation condition 3.1 Altitude:not above 1000m 3.2 Ambient temperature:-15 to 40C 3.3 Relative humidity: up to 85% under 20C. 3.4 Vibrate frequency:between 10 to 150Hz, the Max virbrate accelerate up to 0.5g 3.5 Power grid voltage:Amplitude fluctuation=10%,It assured rated operation. 3.6 Ambient medium:without conductive dust and corresive metal gas to damage insulation. Main technical parameter 4.3 Speed adjust range:1250 to 120(round per minute) 4.4 Speed regulation: up to 0.5%(when 10% to 100% load changes) 4.5 Steady speed accurancy:setting speed lower than 2 round 4.6 Test motor: 3-phase,larger than AC 30V,when motor is at 1500 round per minute. 4.7 Protection device:drag motor to stop,overspeed protection
