GD motor with 1: 42gear 【0～29rpm ⇒ 0～8533Hz(1-2P)】
The characteristic of our Peristaltic Pump products is an initial hight torque value. It's about 2 or 3 times higher
compared to the torque required to maintain a constant velocity once the tube has conformed to the shape of the roller.
When you have a step-motor driven by a high frequency, it is necessary to apply the frequency described in above.
In deceleration, the frequency can be reduced gradually as well as in acceleration or within being cut off suddenly.
One point advice
If Pump load is high and rotor does not work, please try to apply 10-20% higher current than rated current of motor during the acceleration of trapezoidal drive above. Once Pump reaches at the constant speed, please set it back to the rated current.
