Linear Stepper Motors can dramatically reduce cost and save space. There is no coupling, no additional bearing support and no assembly work required. This not only reduce cost but also reduce failure rate due to the less number of components and more simple construction. In applications with small load ratings a linear guide is also not required. The special design and material of the nut secure long life operations.
Below versions can be delivered
- External linear actuator. Nut are mounted on lead screw.
- Captive
- Rolled ball screw, grade C7.
- Non-Captive linear actuator with nut inside motor. Linear moving part can rotate so it should be fixed. (only for NEMA34, IP00)
On request

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 288 W and 6 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 and MIL176
- MIL231 and MIL232
- MIL341
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 MIL series allows connectivity to all industrial Ethernet interfaces such as Profinet, EtherCAT, Powerlink, EtherNet/IP, Modbus TCP and SERCOS III. Interface:
