JVL’s newest high-capacity MAC motors with a rating of 3,000 W are complete servo systems including a high-dynamic ac servo motor, hall-sensors, encoder, power supply, driver and positioning controller and Nano-PLC, as well as facilities for incorporating various control modules such as Bluetooth, WLAN, ZigBee, EtherCAT, EtherNet/IP, CANopen, DeviceNet, Profibus, Profinet, Nano PLC, RS232/RS485/USB, and Process Control, among others.
The MAC motor sets new standards for the performance and size of servo controls. With a length of only 311.8 mm for a 3,000-W motor with a torque of 9.55/28.6 Nm at 3, 000 rpm, this MAC motor matches the size of traditional servo motors without built-in controllers with a flange of 130 x 130 mm. This has only been possible through the use of extremely compact motors and the development of electronics and mechanics that use the latest technologies and manufacturing methods. As with the other integrated servo motors in the range (50 to 3,000 W), both the motor and all electronic components have been specifically selected to withstand the rigorous demands required by industrial use.
Powering this motor is easy since it only requires connection of the main voltage of 3 x 400 Vac through the M23 connectors. Control voltage for the encoder and microprocessor circuitry is 24 Vdc. In an emergency-stop situation, where an approved relay has cut-off the main power, encoder position and other values are maintained by this control voltage. In some applications, however, this is not needed and in those cases an optional internal 24 Vdc supply can be used, requiring only an ac main connection. Highly effective switching technology is used to ensure low heat generation resulting in appreciable energy savings.
One of the big advantages of using the integrated MAC motors is eliminating the need to install a separate servo driver or controller in a control cabinet. This provides many advantages including space savings in control cabinets, saving of expensive motor and encoder cables, saving time (and money) for cabling, noise is minimizing noise due to internal cabling and also eliminating installation errors between driver and motor. In addition, service is much easier because the motor and controller can be replaced as a single integrated unit, minimizing downtime and maximizing production.
