New Integrated Spindle Drive Motor with Absolute Multi-Turn Encoder from JVL

August 30, 2021

JVL A/S is announcing a new addition to its ServoStep™ motors, a directly mountable motor for driving spindles. It’s perfect for replacing hand wheels in format change applications.

All-in-one unit

ServoStep™ has everything built-in including motor, encoder, drive electronics, control electronics with ePLC™ and optional Ethernet or CAN bus integrated into one compact unit. All major industrial Ethernet protocols like Profinet, EtherNet/IP, EtherCAT, SERCOS, ModbusTCP/UDP and Powerlink are available.

Features include

  • Double Ball Bearings enabling up to 7100 N axial load
  • Closed-loop control
  • Energy efficient due to automatic current control 
  • Built-in ePLC™ with 8 DIO, 24V or 0-5V (12bit) analog input with advanced filtering
  • Ultra-high resolution: 409600 step/rev
  • Speed-resolution down to ±0.01 RPM
  • Change speed or torque or other parameters ”on-the-fly” (while driving)
  • Optional: CANopen protocol with DS 301 and DSP 401 support
  • Optional: STO (safe torque off, SIL3)

Below versions can be delivered

  • Rolled ball screw up to 3 meters
  • Captive version up to 127 mm travel length
  • Motor without screw, for mounting of own screws

On request

  • Custom screw end machining
  • Higher IP protection (for motor only)
  • Trapeze lead screw with POM or brass material nut
  • Teflon coating (only Captive version)
