JVL integrated stepper motors

JVL Industri Elektronik A/S has announced NEMA23 integrated stepper motors based on the latest technology and an advancement of the previous designs, incorporating customer feedback.

The integrated motors have an RS485, an optional CANopen or an industrial Ethernet interface as well as an easily programmed motion controller. All the necessary electronics in a stepper system are integrated in the motor. Step resolution is high at 409,600 steps per revolution, resulting in smoothness and silent running.

The user can choose between top or rear end-mounted M12 connectors. The MIS23 motors come in three different sizes and two different motor types — three with standard high-torque stepper motors and two versions with ultrahigh-torque stepper motors with 40% higher torque.

The motors can be operated as stand-alone units or controlled from a PLC or PC. The eight I/Os can be individually configured as digital input, digital output or analog input. It is possible to communicate with systems via, for example, Modbus RTU or CANopen.

The MAC motor standard protocol that is supported makes it possible to connect up to 254 other JVL integrated motors. The MIS23 series allows connectivity to all industrial Ethernet interfaces such as Profinet, EtherCAT, Powerlink, EtherNet/IP, Modbus TCP and SERCOS III.

Speed precision for the stepper motors is 0.01 rpm, while acceleration precision is 1 rpm/s. They can operate from a wide supply range of 7–72 VDC, with motor current of 0–6 A RMS and 8.5 A peak.
