Product Description:

The AKM42J-ACC2EF00 synchronous servomotor manufactured by Kollmorgen works in conjunction with a SERVOSTAR servo amplifier. This motor needs its housing to be earthed safely to the protective earth busbar in the switch cabinet. The product comprises a keyway output shaft. This device features a J-type winding. The unit’s connectors must not be unplugged during operation. Its installation must be done only in a machine for which a hazard analysis has been done. This motor can never be connected directly to the power supply.

The product is to be safeguarded against shock, especially on its shaft end. This device supports a maximum ambient operating temperature of 40 °C. The unit’s enameled finish on the housing is not resistant to solvents. Its holding brake does not support a retrofitting action. This motor has been designed without a shaft seal. The product comprises an electrically isolated PTC. This device has five pole pairs or ten poles. The unit is equipped with three phases. It forms a closed torque or speed control loop along with the supporting servo amplifier.

This motor’s components are to be protected against bending during handling and transport. The product’s capacitors have a dangerous voltage for a brief period after it has been disconnected from the power supply. This device’s casing must be earthed to the mounting plate. The unit connection is done with the manufacturer’s preassembled cables. Its setup can be done only after checking its orientation and assembly. This synchronous servomotor’s holding brake has a 24 VDC voltage rating and cannot be used to ensure the safety of the operating personnel.
