Product Description:

The AM8542-0E20-0000 is a synchronous servo motor built by Beckhoff and assigned to the AM Synchronous Servo Motors series. In industrial automation, it acts as an electromechanical actuator that delivers commanded motion profiles to packaging machines, assembly robots, and general material-handling equipment. When it is coupled to gear trains or mounted directly to driven shafts, the unit provides precise angular displacement under servo control, supporting accurate positioning, repeatable speed regulation, and rapid dynamic response in multi-axis systems. This makes it suitable for synchronized axes that must accelerate, decelerate, and hold commanded speed without noticeable lag during cycle changes.

Its electrical interface is provided through a rotatable angular connector, which allows cable routing in different directions, and a terminal box can also be used for fixed conduit entry. Rotor position and turn count are monitored by an OCT multi-turn encoder, so the drive retains absolute position data after power loss. Absolute feedback also reduces the need for a reference move after restart in many machine layouts. A flange that measures 87 mm across centers fits standard square mounting patterns. Because the motor is supplied without a holding brake, any static load must be secured by the drive or an external locking device. The rotor uses an increased mass moment of inertia, which gives higher kinetic energy storage to smooth speed fluctuations during heavy load changes. This configuration is offered as the Standard version.

The overall length code 2 keeps the motor body short enough for compact machine frames while still leaving room for the assigned winding arrangement. The winding code E indicates the electrical and thermal characteristics used for this motor configuration. Power is delivered through a smooth shaft, so torque is transmitted by clamping couplings rather than keyways. That shaft style is suited to applications that use friction-locking hubs and do not require a keyed connection.
