Product Description

Beckhoff manufactures the AM3042-0E21-0000 servo motor. This device has a nominal voltage of 480 V AC and a torque constant of 1.26 Nm/A. The motor also has a standstill torque of 3.42 Nm and a rated torque of 2.81 Nm. The rated speed is 3500 min^-1, with a peak torque of 13.0 Nm. The rated power is 1.03 kW. The standstill current is 2.74 A, with a peak current of 13.7 A. The rotor moment of inertia is 1.450 kgcm². The motor feedback is a resolver, BiSS B, and EnDat 2.1. The AM3042-0E21-0000 is convection-cooled and features an M23 connection method. The ambient temperature during operation is +5…+40 °C. The temperature of the winding is monitored by temperature sensors in the stator windings and is signaled via an electrically isolated contact (normally closed). The thermal contact integrated into the motor windings must be observed and evaluated.

The motor length changes when an encoder is mounted. The permitted mounting positions may be read from the technical data of the motor series. Power transmission is made through the cylindrical shaft end (fit k6) to DIN 748, with a locking thread but without a fitted keyway. High radial forces will occur if the motors drive via pinions or toothed belts. The maximum values at the rated speed can be found in the technical data section of the source document. Power take-off from the middle of the free end of the shaft allows a 10% increase in radial force. The axial force must not exceed ⅓ of the radial force. Double-coned collets have proved to be ideal zero-backlash coupling devices, combined, if required, with metal bellows couplings.

Flange dimensions are based on the IEC standard (fit j6, accuracy according to DIN 42955). The tolerance class is R. The standard version of each motor is fitted with a thermostat (electrically isolated, normally closed). The switching point can be found in the technical data section of the source document. The thermostat does not provide any protection against short, heavy overloading. Provided that the pre-assembled resolver cable is used, the thermostat contact is integrated into the monitoring system of the digital servo amplifier AX2000. Wake Industrial offers a one-year warranty when purchased.
