ServoStep NEMA17 Integrated Linear Stepper Motor up to 1100N with integrated controller

PRESS release: May 2021

Birkerød, Denmark - JVL A/S, one of the world leaders in the field of integrated servo - and stepper motors introduce a new compact and slim Captive, Non captive, External nut integrated linear stepper motor. The new ServoStep integrated linear stepper motor series MIL171 to MIL176 have a NEMA17 42x42mm flange and include controller with 6 different industrial Ethernet protocols, absolute multiturn encoder, closed loop and M12 connectors. This new motor family is based on the latest microprocessor and cooling technology and an advancement compared to previous designs.
All the necessary electronics in a stepper system are integrated in the motor itself and are similar to the concept used by other JVL motors, making it very easy to use in all kind of motion control stepper or servomotor applications.
The motor contains everything needed to solve a modern control task, either as a stand-alone with own easy programmable motion controller or controlled from an external PLC or PC. 8 I/O points can be individually configured as digital input, digital output or analogue input. Modbus RTU or CANopen provide easy connections to a PLC or HMI. An ActiveX/OCX driver is available to make simple interface to LabView, Excel, VB or other Windows-programs. Up to 254 axis can be connected on the same RS485 bus

Key mechanical features:
  • Captive, Non-captive, External nut
  • Lead screw or Ball screw
  • 90 to 1100 N
  • Customer can replace screw
  • Customer can choose screw supplier
  • Lead screw from 0.6 to 25 mm/rev
  • Optional Front mount brake
  • Protection class housing and screw up to IP65
  • Standard M12 or optional M23 connectors
Key electronics features:
  • Industrial Ethernet. 6 Protocols
  • Very high motor power and torque
  • Closed-loop operation with current control
  • Very high efficiency= low temperature rise
  • Absolute multiturn encoder
  • Safe Torque Off (STO) input TUV approved.
  • High resolution 409600 cnt/rev.
  • Speed 0-3000 in 0.01 RPM steps
  • Wide supply range 7-72 VDC
Industrial Ethernet:
Profinet, EtherCAT, Powerlink, EtherNet/IP, Modbus TCP or SERCOS III are available and for EtherCAT and SERCOS III synchronization and drive profiles are available. MACtalk can use Ethernet for comMILsioning the motor so no need for RS232/RS485 converter or additional cables. The motor has the ability to be upgraded with other protocols or newer versions of the same protocol at any time. Because of the upgradeability, the JVL Industrial Ethernet module is also ‘future proof' as newer versions of the protocols will always fit into the design. The motor is equipped with two Ethernet connectors and a built-in switch, enabling line topology without any extra expensive hardware. Several LEDs, enabling technicians and operators to get a quick status overview
New Technology:
JVL has used the latest technology to achieve the incredibly high step resolution of 409,600 step/revolution, resulting in unsurpassed smoothness and silent running. At the same time reached an incredible speed-precision 0.01 RPM and acceleration precision 1 RPM/sec that have not been seen before.
The newly developed heat transfer system, power electronics and special motor windings offer very high efficiency and optimized for outstanding high peak power up to 100 W and 1 Nm.
Closed-loop provides higher torque, faster acceleration, current control, stall free operation and quieter operation compared to more traditional step motor systems. It compensates and corrects step angle error during a movement with a 36 Mhz update rate within a full step thereby it works like a perfect stepper motor benefiting from the servo motor technology.
Motor range:
  • MIL171 up to 720 N
  • MIL173 up to 900 N
  • MIL176 up to 1100 N
The motors can be operated as stand-alone units or controlled from a PLC or PC. The 8 I/Os can be individually configured as digital input, digital output or analog input. As standard, it is possible to communicate with holistic systems via for example Modbus RTU or CANopen. The MAC motor standard protocol that is also supported makes it possible to connect up to 254 other JVL integrated motors. The MIL17 series allows connectivity to all industrial Ethernet interfaces such as Profinet, EtherCAT, Powerlink, EtherNet/IP, Modbus TCP and SERCOS III.
  • Industrial Ethernets Profinet, EtherCAT, Powerlink, EtherNet/IP, Modbus TCP and SERCOS III
  • CANopen DSP402 and DS301
  • Pulse/Direction mode for electronic gear
  • High speed position capture
