Product Description:

The AM8042-0JH1-0000 belongs to the AM Synchronous Servo Motors series from Beckhoff and is used as a compact rotary actuator for positioning and velocity control tasks in automated machinery. By combining permanent-magnet rotor technology with integrated digital feedback, the motor delivers precise closed-loop motion. It fits directly into EtherCAT-based drive architectures found on many production lines.

The integrated 24 V holding brake is energized through a brake supply of 24 VDC, allowing the shaft to remain locked when power is removed. Position monitoring is handled by an OCT multi-turn encoder that reports absolute positions with 24-bit resolution, so no homing cycle is required after each startup. Mechanical attachment follows an IEC-compatible 87 mm flange, while torque retention during standstill reaches 9 Nm, permitting vertical-axis use in moderate load ranges. Wiring is simplified because power and signal leads exit through a rotatable angular connector or an optional terminal box, and this swivel capability eases cabinet layout. The motor is cataloged as the Standard variant in the series, carries the Overall Length Code 2 for medium housing depth, and employs winding code J to match Beckhoff AX5000 inverters.

Functional safety is addressed by compliance with SIL 2, making the unit suitable for systems that implement safe torque off or safe stop functions without additional encoders. A smooth shaft design avoids keyway-induced concentricity errors and supports clamp or friction couplings often found on high-precision actuators. The winding set identified by code J balances current demand against thermal limits, allowing continuous operation without external cooling. Within the Synchronous Servomotors product family, this combination of brake control, high-resolution feedback, and standardized mechanical dimensions gives builders a uniform platform for multi-axis assemblies while leaving installation flexibility through the selectable connector orientation.
