Product Description:

The AM227M-0000 is a compact synchronous servo motor built by Beckhoff within the AM Synchronous Servo Motors series. Intended for industrial automation, the unit transforms drive output into regulated rotary motion for positioning or velocity control in packaging machines, pick-and-place stations, and light assembly equipment. A two-pole resolver supplies analog position feedback that remains resistant to electrical noise, helping the drive maintain reliable commutation after power cycles. The motor is suited for compact motion axes that require precise speed and position control.

In continuous operation, the motor delivers 0.13 kW of mechanical power while spinning at up to 4000 rpm. This output draws 0.75 A of phase current and produces a nominal torque of 0.3 Nm. The motor has a torque constant of 0.41 Nm/A, allowing the servo amplifier to predict torque from measured current. For short acceleration bursts, the winding can accept 3.5 A, enabling rapid speed changes without magnetic saturation. The 10-minute thermal time constant shows how quickly internal temperature follows load variations, and the design without a holding brake reduces passive drag on the rotor.

During standstill, the motor can resist external loads with 0.32 Nm of torque while the standstill current stays at 0.8 A, and static friction is limited to 0.02 Nm for smooth starts. Low standstill friction helps the shaft start smoothly during repeated indexing cycles. The rotor inertia of 0.08 kg cm² supports fast indexing with limited overshoot. The motor has a 194 mm flange and a smooth shaft, and it accommodates axial forces up to 30 N and radial forces up to 90 N. Electrical behavior at low frequency is influenced by a phase inductance of 21 mH and a winding resistance of 31 Ω, which the drive uses for voltage feed-forward. The complete assembly weighs 1.1 kg. External clamping is required when power is removed.
