JVL expands line of integrated spindle drive motors with absolute multi-turn encoders

JVL A/S has introduced a new addition to its ServoStep line of motors, a directly mountable motor for driving spindles. It’s perfect for replacing hand wheels in format change applications. 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 7,100 N axial load
• Closed-loop control
• Energy efficient due to automatic current control 
• Built-in ePLC with 8 digital I/O, 24 V or 0-5 V (12-bit) analog input with advanced filtering
• Ultra-high resolution: 409,600 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 m
• 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)
