Product Description:

Beckhoff manufactures the AM3042-0G40-0000 within the AM Synchronous Servo Motors series, supplying a rotary actuator intended for closed-loop automation axes where position accuracy and compact dimensions are required. By integrating with EtherCAT drive controllers, this motor delivers precise torque modulation for pick-and-place gantries, packaging stations, and CNC auxiliary axes across industrial machinery. Its synchronous design supports repeatable starts, stops, and reversals in machine sections that need responsive motion without taking up excessive installation space.

The mechanical interface uses an 87 mm square flange, allowing direct mounting to gearboxes or machine frames without adapter plates. Power and feedback lines exit through a rotatable angular connector or terminal box, and this arrangement helps route cables without sharp bends at the motor housing. Position data comes from a Hiperface multi-turn 128 SinCos encoder, so the drive can track rotor angle over 4096 revolutions and retain accurate motion feedback through normal operating cycles. A smooth shaft avoids keyways, which helps reduce fretting during frequent reversing duty and supports clamp-style couplings. The actuator is supplied without a holding brake, so stationary torque must be provided by the drive or by external locking devices on vertical axes.

Electrical and thermal behavior follows the motor’s G winding, which sets phase resistance and inductance for use with Beckhoff AX5xxx inverters. Physical depth corresponds to length code 2, giving a balance between continuous output capability and the axial space available in dense multi-axis layouts. The motor uses the standard series type, so it follows the usual AM-series layout for laminations, magnets, and cooling paths. It is also the standard version and is intended for clean industrial environments where ambient temperatures remain within the published operating range.
