R911272880
The R911272880 (MDD093C-N-040-N2M-110PB2) is an AC servo motor developed by Bosch Rexroth Indramat, it falls under their MDD series of digital motors. Compatible with drive controllers such as the DDS series from Bosch, these motors come with an optional blocking brake. Operating at 24 volts DC and drawing 0.7 Amps, this electrically released brake weighs 1.1 kg and has clamping and release delays of 30 and 70 milliseconds respectively. Furthermore, MDD093 motors offer brakes with 11 Nm holding torque. The motor is designed to operate within a temperature range of 0 to 45 degrees Celsius, with output reducing at higher temperatures.
The motor is suitable for use at altitudes of up to 1000 meters, with output reducing at higher altitudes. For storage and transport, it can tolerate temperatures between -20 to 80 degrees Celsius. The motor housing has an IP65 protection category, ensuring dust proofing and moisture protection. Over the black prime coat (RAL 9005) surface, an additional layer of paint can be applied. The R911272880 (MDD093C-N-040-N2M-110PB2) comes with features such as a shaft with keyway, a multiturn absolute encoder, and a power connection on side B. The integrated encoder facilitates digital servo feedback. Its nominal motor speed is 4000 RPM and the housing is adapted for natural convection or surface cooling.
