Product Description:

The AM227L-0000 is a rotary motor manufactured by Beckhoff and assigned to the AM Synchronous Servo Motors series. It serves as the electromechanical element that delivers controlled motion in automated machinery, receiving drive power from a 400 V AC supply and providing precise shaft positioning through resolver-based feedback. The motor is suited to compact servo axes where repeatable speed control and accurate positioning are required during continuous machine operation.

During continuous operation, the motor reaches a rated speed of 4500 rpm while producing 0.72 Nm of torque. Power drawn at that point equals 0.34 kW, and the electrical demand on the drive is only 0.83 A, which helps with inverter and cable sizing. A flange diameter of 194 mm establishes the mounting interface on the machine frame. Standstill torque is specified at 0.8 Nm, indicating the available holding torque before rotation begins. Rotor inertia of 0.13 kg·cm² supports rapid acceleration with minimal overshoot. The motor has a smooth shaft, and the permissible radial and axial loads of 115 N and 40 N set the allowable belt or coupling forces. Winding inductance of 43 mH and resistance of 47.7 Ω affect current ripple and thermal rise, and the unit is supplied without a holding brake.

Short-duration transients can be handled with a peak phase current of 3.8 A, giving additional torque margin above the continuous rating. The torque constant of 0.96 Nm/A links commanded current to output torque, while a back-EMF constant of 58 V/1000 rpm indicates the voltage generated during regeneration. Thermal behavior is modeled by a time constant of 22 min, allowing predictable temperature rise under cyclic duty. Resolver feedback with two poles supplies rotor angle information for closed-loop control. The total mass is 1.5 kg, which supports lightweight axis designs without reducing the stated load capacity.
