ServoStep: the next-generation NEMA23 integrated stepper motors

JVL Industri Elektronik A/S is announcing a completely new generation of the NEMA23 integrated stepper motors that have proved their value for many years. The new motor family, ServoStep, uses the newest technology and the advancement of the previous designs, incorporating customers' feedback. The family has the widest pallet of options in the market and will thus fit into all possible customer applications.

Integrated motors mean you get an all-in-one package. In one unit you get motor, drive electronics, encoder, motion controller and an easily programmed embedded PLC with 8 I/O points onboard. The motors can operate as stand-alone units or be controlled from a master PLC or PC. The 8 I/O points can be individually configured as digital inputs, digital outputs or analogue inputs.

Even without options the new ServoStep motors offer some very strong features such as closed-loop operation, torque control, ultra-high resolution of 409600 step/revolution resulting in unsurpassed smoothness and silent running plus a wide speed range from 0-3000RPM with an extreme resolution of just 0.01RPM.

Power supply goes from 7 to 72V DC and there are 4 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 per cent higher torque. There are 10 different motors with 0.97Nm to 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 - well suited for AGVs and other battery supplied applications.

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.

For cabelling, 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.
