Closed-Loop Integrated Stepper Motors Feature Magnetic or Absolute Encoder Feedback

JVLJVL presents a new closed-loop stepper motor technology for its NEMA 23 & 34 integrated stepper motor range from 0.1 to 12 Nm. JVL has developed a unique product in the field of integrated motor control.

JVL closed-loop integrated stepper motors, QuickStep, provide higher torque, faster acceleration, torque control, stall free operation and quieter movements than traditional step motor systems. QuickStep do this with greater efficiency and less motor heating because motor phase current are regulated up and down according to need. Performance of JVL closed-loop steppers are similar to servo motors, but with higher torque and often without need of gearbox, resulting in a more inexpensive solution. Design safety factors have always been high for stepper motors to ensure stall-free operation, now with QuickStep closed-loop control design can be very close to the limit resulting in even lower costs. QuickStep is a true closed-loop control system that compensates step angle errors during a movement and correct errors within a full step. If load becomes too high speed is lowered and position errors will always stay within two full-steps. Smart digital design and very high update rates (36 MHz) means there is no need of any manual adjustment or setup. It works like a perfect stepper motor benefiting from the servo motor technology.
