Product Description:
The AM3042-0E21-0000 is a synchronous servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. Designed for closed-loop drive systems, the unit converts electrical input into controlled mechanical rotation for positioning axes, pick-and-place modules, and packaging stations. Its compact geometry and integrated feedback support repeatable torque and speed control, which makes it suitable for automated equipment that depends on accurate starts, stops, and direction changes during continuous operation.
In operation, the motor’s braking system uses a dedicated 24 VDC brake voltage, permitting controlled shaft locking when drive power is removed. Position data is returned through integrated OCT multi-turn feedback, so the controller can track absolute rotor position across multiple revolutions without relying only on incremental counts. Mounting uses an 87 mm flange, which supports installation on common machine interfaces in this frame class. The motor also has a smooth shaft, which works well with clamp couplings and avoids the keyway features used on keyed shaft designs. When the brake engages, the motor can resist up to 9 Nm holding torque, which is suitable for moderate vertical loads and other axes that must remain in place at standstill.
Cabling exits through a rotatable angular connector, which helps when installation space is restricted and cable direction must be adjusted at the motor. Mechanical holding is provided by a 24 V holding brake mounted at the rear of the housing, matching the low-voltage control supplies commonly used in industrial systems. The electromagnetic design uses winding code E, which matches the stator characteristics to compatible Beckhoff drive amplifiers. The motor has overall length code 2, giving it a mid-length housing that balances compact installation with usable continuous output. It is supplied in the standard version of the series and uses the insulation system, thermal limits, and connector geometry associated with this standard motor type.
