MAC4500 is the complete solution for larger power ratings designed by JVL. All with built-in mains power supply, 3x400/480 VAC. RMS power 4500 W. Now with new high efficient servo motor with continuous 15Nm and up to 13Kw peak power. The motor is equipped with M23 connector for harsh industrial use up to IP67 protection. Controller, PLC, encoder, power supply and bus system are integrated in one unit. Optional industrial Ethernet, fieldbus, IP protection class, abs. multiturn encoder, brake and much more. MAC motor®s are complete servo systems including a high-dynamic AC servo motor, hall-sensors, encoder, power supply, driver and positioning controller, as well as facilities for incorporating various control modules such as Bluetooth, WLAN, ZigBee, EtherCAT, EtherNet/IP, CANopen, DeviceNet, Profibus, Nano PLC, RS232/RS485/USB, Process Control, etc.
New Compact Motors
The MAC motors set completely new standards for the performance and size of servo controls. With a length of only 182 mm for a 1500 W motor with a torque of 4.78/14.3 Nm at 3000 rpm — and 232 mm for a 3000 W motor with a torque of 9.55/28.6 Nm at 3000 rpm, these MAC motors match the sizes of traditional servo motors without built-in controllers with flange 130x130 mm. This has only been possible through the use of extremely compact motors and the development of electronics and mechanics that utilise the latest technologies and manufacturing methods.
So what about vibrations and temperature? As with the other integrated servo motors in the range (50…3000 W), both the motor and all electronic components have been specifically selected to withstand the rigorous demands required by industrial use.
Power Supply and Energy Savings
Powering these motors 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.
Furthermore highly effective switching technology is used to ensure low heat generation resulting in appreciable energy savings.
