R911275029
The R911275029 (MDD093B-F-020-N2L-110GA1) is an AC servo motor from Bosch Rexroth Indramat's MDD series, fully equipped with digital servo feedback and a specially designed blocking brake. This brake, electrically triggered to release and function with an operational torque of 11 Nm, is designed to prevent inadvertent shaft start-ups when the motor is in standstill condition. Additional technical specifications of the brake include a rated current and voltage of 0.5 Amps and 24 Volts DC, respectively, with a moment of inertia of 0.0106 kg m2 for the brake. The combined weight of the motor and brake is 17 kilograms, with individual weights of 16.5 and 0.5 kilograms respectively. The cooling system of the motor operates on natural convection or surface cooling with a thermal time constant of 50 minutes for the former and 45 minutes for the latter.
Performance-wise, the R911275029 (MDD093B-F-020-N2L-110GA1) operates at a nominal speed of 2000 RPM, delivering a continuous torque of 14.5 Nm and current of 16.9 Amps at standstill with natural convection; and 20 Nm and 23.3 Amps with surface cooling. The motor can operate in ambient temperatures between 0 to 45 degrees Celsius, with a protection rating of IP65 to safeguard against dust penetration. The housing of the motor includes a power connector at side A and a plain main shaft with a centering diameter of 110 millimeters. Please ensure only trained and skilled technical staff are engaged in its installation and operation, and the motor should not be used outside the specified conditions to ensure optimum performance and longevity.
