The new motors use the same driver, controller, ePLC™ and Ethernet PCB as the motors that have been on the market for many years. It is the raw motors that have been redesigned with new plastic bobbin and additional insulation to fulfill the UL requirements. UL in Denmark and Italy have helped with the development to achieve a completely new raw motor and electronics with special UL insulation. Three different stack sizes MIS231, MIS232 , MIS234 have been developed inclusive 2 with permanently magnet so in total 5 different ServoStep™ NEMA23 models will be available with UL approval. The motor can be used up to 60VDC supply voltage with UL approval and up to 72VDC for non UL applications. Delivery of the new motor will be available later in 2022.

 

The new motor family, ServoStep™, uses the newest technology and the advancement of the previous designs, incorporating customers’ feedback for many years. The family has the widest range of options in the market and will thus fit into all possible customer applications. Apart from the UL redesign the current and regulation filters have been improved so motors can now deliver more torque at high speeds resulting in a remarkable performance increase compared to previously models.

 

First of all, integrated motors mean you get an all-in-one solution. In one unit you get motor, drive electronics, encoder, motion controller and an easily programmed embedded PLC (ePLC™) 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 like 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 0-3000 RPM with an extreme resolution of just 0.01 RPM and high torque even at 3000RPM.  
Power supply goes from 7 to 72 Volt 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% higher torque. There are ten different motors with 0.97 Nm to 3.1 Nm.

 

Popular options include: Absolute multiturn encoders, CANopen, double shaft, hollow shaft, electromechanical brakes (front or rear mounted), better IP protection class up to IP65/IP67, special customized connectors and Safe Torque Off (STO) input. Even wireless options exist: Bluetooth and WLAN – ideal for AGVs and other battery supplied applications.

 

Ready for Industry 4.0 and IIoT (Industrial IoT)

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.
Cabling is a hassle? Using the onboard Ethernet-switch you can daisy-chain cables from one motor to the next. Quite uniquely on the market, users can even change Ethernet protocol by updating the firmware using the MacTalk software
