Next-gen integrated stepper motors are silent running

Integrated servo and stepper motor producer, JVL Industri Elektronik, has announced a new generation of the NEMA23 integrated stepper motors. The new motor family, ServoStep, uses the newest technology and the advancement of the previous designs, incorporating customers’ feedback. According to the company, the family has the widest pallet of options in the market and will thus fit into all possible customer applications.

Key features
First of all, integrated motors mean you get an all-in-one solution. In one unit you get the motor, drive electronics, encoder, motion controller and an easily programmed embedded PLC with eight I/O points onboard. The motors can operate as stand-alone units or be controlled from a master PLC or PC. The eight I/O points can be individually configured as digital inputs, digital outputs or analogue inputs.

Even without options the new ServoStep motors offer some strong features like closed-loop operation, torque control, ultra-high resolution of 409600 step/revolution resulting in smoothness and silent running plus a wide speed range from 0-3,000 RPM with an extreme resolution of 0.01 RPM.

Power supply goes from 7-72VDC and there are four pcs M12 industrial connectors for supply, signals and communications. Serial RS485 interface is standard on all motors.

The family base line consists of high torque motors but if even more is needed JVL offers ultra high torque motors with up to 30% higher torque. There are ten different motors with 0.97-3.1Nm.

Popular options include: Absolute multiturn encoders, CANopen, double shaft, hollow shaft, electromechanical brakes (front or rear mounted), better IP protection class up to IP65, special customised connectors and Safe Torque Off (STO) input. Even wireless options exist: Bluetooth, Zigbee and WLAN – suitable for AGVs and other battery supplied applications.

Ready for Industry 4.0 and IIoT
All ServoStep motors can be delivered with industrial Ethernet onboard. You can choose among all major protocols: Profinet, EtherNet/IP, EtherCAT, Sercos III, Powerlink and ModbusTCP/UDP.

No matter which Ethernet protocol were chosen for the machine or the whole factory the ServoStep motors can be connected.

Cabeling is a hassle? Using the onboard Ethernet-switch you can daisy-chain cables from one motor to the next. Users can even change Ethernet protocol by updating the firmware using the MacTalk software.
