JVL presents a new closed-loop stepper motor technology for its NEMA 23 & 34 integrated stepper motor range from 0,1 to 12 Nm. JVL, the European leader in the development of integrated servo and stepper motor technology, has again developed a new and 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.
Features include:
- Motor phase current regulated up and down according to need
- Higher torque than servo motors and often without need of gearbox, resulting in a more inexpensive solution
- True closed-loop control system compensates step angle errors during a movement and correct errors within a full step
- Smart digital design and very high update rates (36 MHz) means there is no need of any manual adjustment or setup
- Position feedback and control
- No stalling. No step losses at all
- Torque control
Advantages compared to servo motors:
- Very high Torque at low speed. Often 3-4 times higher in same motor flange size
- Very high ratio-of-inertia, often up to 40:1
- Faster commissioning. No tuning needed
- Lower price. Same price as open loop steppers
- Totally stiff at standstill. Full holding torque
- Direct drive without gearbox (better and more precise torque control)
- Correct positioning without overshoot
- No oscillation
- Very short settling time
Benefit in these application from closed-loop stepper motors:
- Multiple axis applications (RS485, CANopen)
- Industrial Ethernet: Profinet, EtherNet/IP, EtherCAT, Powerlink, Modbus TCP, SERCOS III
- Magnetic or Absolute Encoder Feedback
- Positioning tasks with load changes
- Applications that require quiet operation, short settling times and precision positioning
Applications include
- Winding applications
- Belt drives (start/stop, positioning)
- Dosing pumps and filler systems
- Semi-conductor mounting
- Wafer production
- Textile machines and industrial sewing machines
- Robotics
- Testing and inspection systems
