AM2xxx | Synchronous Servomotors
The AM2000 series of brushless Synchronous Servomotors are of outstanding quality; they are highly dynamic, the rotors have low moments of inertia, they have excellent rotational characteristics and impressive overload capacity. The Synchronous Servomotors, in connection with digital Servo Drives from the AX2000/AX2500 series, are excellently suited for positioning tasks that make high demands on dynamics and stability. The servomotor rotors are fitted with neodymium permanent magnets. This magnetic material is an important factor in making it possible to drive these motors in a highly dynamic fashion. The motors are fitted with two-pole hollow shaft resolvers and as an option may be obtained with a holding brake.
Temperature sensors in the stator windings and corresponding signal output via a zero-potential (break) contact monitor the coil temperature. The motors normally have an integrated resolver to provide feedback (optional single-turn or multi-turn absolute encoder). The Servo Drives evaluate the feedback signals and feed sine-wave currents to the motors.
The motors have angled connectors for the power supply and the feedback signals. Beckhoff offers the resolver, encoder and power leads as a ready-assembled accessory.
The motors are optionally available with an integrated stop brake. This holding brake (24 V DC) locks the rotor when power is removed. When the brake is released, the rotor can turn without residual torque. Operation is free from backlash. The stop brake can be driven directly by the Servo Drive.
