New integrated, intelligent motors from Denmark’s JVL Industri Elektronik

Birkerod, Denmark–JVL Industri Elektronik A/Shas recently introduced what it calls ”a completely new concept in motor control.” Designated the MAC motor, this development combines an ac servo motor, controller, Hall-effect sensor, and encoder in a single compact unit ”that offers true servo performance” and ”previously unseen low price.”

Beside allowing distributed intelligence, this type of integrated design offers the advantages of simple installation by eliminating cabling between motor and driver, as well as costly space requirements in control cabinets.

MAC motor operates in either speed or torque control mode viausing Microsoft Windows-based software. Operating commands from the PC or PLC also come through RS-232/485.

JVL’s design uses a so-called “fourth-order regulator,” which is said to provide such user benefits as a stiffer system with shorter positioning times; ability to avoid oscillations from mechanical system nonlinearities; and minimizing of positioning error. Overall, this leads to shorter installation and startup times.

Presently, MAC motor is available in three models rated at 50, 95 or 140 W, and operates on 24-48 V dc input. A standard NEMA 23 flange further eases direct replacement of an existing step motor without mechanical modifications. All motor models have provision to mount a planetary gearhead with ratios of 3, 5, 10, 20 or 100:1. Several modules for PLC and communication network interfaces expand user applications.

MAC motor represents a small but growing class of integrated, intelligent motor and control (I2MC) products that now provide more choices for motion control system developers and users.
