Product Description:
The R2AA06040FXS00M is a medium-inertia servo motor manufactured by Sanyo Denki within the R SANMOTION Servo Motors series. Designed for closed-loop positioning in automated machinery, the unit couples directly to gearboxes or linear stages through a compact mounting flange, allowing installation on robots, conveyors, and indexing tables. A wire-saving incremental encoder with 2,000 pulses per revolution provides the drive controller with real-time shaft feedback, while compliance with CE and UL requirements supports installation in international control panels. The motor is supplied without a holding brake, so an external mechanism must secure vertical loads when power is removed.
The stator is wound for a rated mechanical output of 400 W at a nominal speed of 3,000 rpm, delivering 1.27 N·m of continuous torque. Its square housing has a 60 mm flange that supports accurate alignment with compatible mounting patterns. Power is supplied from a 200 V bus through a three-phase connection, and the rotor inertia of 0.412 × 10⁻⁴ kg·m² balances rapid acceleration with stable settling during point-to-point motion. A torque constant of 0.524 N·m/Arms converts commanded current into predictable drive torque, while the encoder signal supports smooth velocity control and precise positioning. The combination of moderate rotor inertia and responsive feedback helps the motor maintain controlled motion when axis speed or load changes rapidly.
The motor can operate at speeds up to 6,000 rpm for rapid traverse moves, and its peak stall torque reaches 4.8 N·m, allowing it to handle momentary load spikes without stalling. Its total weight is 1.4 kg, which reduces the added mass on moving axes where mechanical load can affect servo response and acceleration. The copper windings have a phase resistance of 1.36 Ω, enabling the drive to monitor changes associated with winding temperature. Continuous torque supports steady operation under sustained loads, while the available peak torque provides additional force during brief acceleration or disturbance events. These operating characteristics suit positioning tasks in packaging equipment, pick-and-place systems, and compact transfer stations where controlled acceleration and repeatable motion are required.
