400-W continuous integrated servo motor

Designed for battery-powered and low-voltage applications, the MAC402 servo motor is now available from JVL (Denmark). According to the company, this is presently the only 400-W servo motor in the supply range of 24 VDC to 48 VDC operating at 0 to 3000 RPM.

IT IS THE VDC VERSION OF THE MAC400 400-W integrated servo motor. The supply range ranges from 12 VDC up to 48 VDC, and full power of 400 W (RMS) up to 1200 W (peak) can be reached with 24 VDC to 48 VDC. The motor measures 191 mm x 60 mm x 114 mm. Applications include but are not limited to: remotely operated robots, robotic vehicles, portable equipment, tracking devices, antenna mounts, and positioning devices. In many applications it is not necessary to choose a 750-W or larger motor as the 400-W motor will be sufficient.

Options include: Brake, absolute multiturn encoder, and planetary & cycloidal gearheads. The user can choose between models with or without brakes. A selection of communication modules is available for the motors including: Basic modules for pulse-direction (or analog input) or fieldbus modules including CANopen. Programmable modules with easy connections to local sensors make integration into applications possible. A variety of industrial Ethernet options are also available.
With the VDC supply option the advantages of the MAC400 VAC servos have been expanded to include applications for battery and low voltage operation, from 12 VDC to 48 VDC. With wireless options like Wlan/Wifi, Zigbee or Bluetooth, the motor can run completely wireless. It features protection level IP55 as standard, with IP66 optional, and it can function as an absolute multiturn encoder without battery. It also offers two RS422 channels for encoder in/output and SSI encoders etc, as well as six I/Os for capture of position, interrupt, counters, enable, timer and PLC functions.

An advantage of using an integrated motor is that there is no need for a separate servo driver/controller. The advantages are: Space savings in the control cabinet, eliminating expensive motor and encoder cables, RFI/EFI noise is minimized due to internal cabling, and connection errors between driver and motor are eliminated. Additionally, service is much easier as the motor and controller are replaced as a single integrated unit minimizing downtime and maximizing production.
