Product Description:
The R2EA04008FCP00M is an AC servo motor produced by Sanyo Denki for the R SANMOTION Servo Motors series. Classified as a medium-inertia unit, it is intended for precise position and speed control in compact industrial axes, including small pick-and-place heads, inspection tables, and light conveyor sections. Its integrated feedback system supports accurate motion during rapid acceleration and deceleration, while the brake prevents unintended shaft movement after power is removed.
The motor operates with a rated armature voltage of 100 V and provides a continuous mechanical output of 0.08 kW. At its rated operating point, the shaft delivers continuous torque of 0.255 N·m. The phase resistance is 2.9 Ω, which affects current flow and winding losses during operation. Its torque constant is 0.22 N·m/Arms, providing a proportional relationship between supplied current and generated torque. The electrical time constant is 0.81 ms, allowing current to rise quickly in response to amplifier commands. A mechanical time constant of 0.98 ms supports responsive speed changes and high-bandwidth servo control.
For brief periods of increased demand, the motor can produce a peak torque of 0.86 N·m. The rotor can operate at speeds of up to 6000 rpm, making the motor suitable for fast indexing and short-cycle motion. A spring-applied brake powered by 24 VDC secures the shaft when brake power is removed, and the battery-backed absolute encoder retains position information while the system is turned off. The motor uses a 40 mm square flange for mounting in compact machinery. Its rotor inertia is 0.0627 × 10⁻⁴ kg·m², balancing rapid acceleration with practical load matching. The enclosure has an IP67 ingress protection rating, which prevents dust entry and protects the motor against temporary water immersion. CE and UL approvals support installation in equipment subject to applicable regulatory requirements. The back electromotive force constant is 7.7 mV per rpm, providing voltage feedback proportional to rotor speed during operation.
