Product Description:
The R2AA08075FXPHV is a medium-inertia AC servo motor produced by Sanyo Denki for the R SANMOTION Servo Motors series. In automated equipment, it converts electrical power from an AC drive into controlled mechanical torque for positioning systems and speed-regulated transport axes. The 80 mm square flange allows the motor to mount on standard machinery frames. Its sealed housing protects internal components, while the battery-backed absolute encoder retains shaft-position data when system power is removed. This position information allows the motion controller to resume operation without requiring the axis to complete a homing cycle.
At its nominal operating point, the motor provides a rated torque of 2.39 N·m and an output of 750 W at 3000 rpm. A continuous stall torque of 2.55 N·m helps the axis remain stable under a sustained static load, while the peak stall torque of 8.5 N·m supports brief acceleration and overload demands. The windings draw 4.6 A RMS from a 200 V bus, so the connected drive must support the required current and voltage. A phase resistance of 0.4 Ω affects winding losses during continuous and intermittent operating cycles. The torque constant is 0.559 N·m/A RMS, providing a proportional relationship between commanded current and shaft torque. The voltage constant of 19.5 mV/rpm indicates the back electromotive force returned to the inverter as motor speed increases.
High-speed indexing is supported by a rotor inertia of 1.823 × 10-4 kg·m², balancing responsive acceleration with load stability. The motor can operate at a maximum mechanical speed of 6000 rpm, providing additional speed range above its nominal operating point for short indexing movements. Position feedback is supplied by a 17-bit encoder, giving the drive sufficient resolution for precise incremental motion and accurate settling. The absolute feedback system also provides shaft-position information immediately after power is restored. The motor has no holding brake, so a vertical axis must use drive-generated torque or an external clamp to prevent movement during a power loss. Load-retention measures should therefore be incorporated wherever gravity or external forces can move the unpowered shaft.
