Product Description

The MDD071A-N-040-N2S-095GA1 is a servo motor from Bosch Rexroth’s MDD product line. It supports digital servo feedback. The motor encoder measures motor parameters including speed, torque and position. The motor sends these measurements in real-time to the servo controller. The controller adjusts its output to bring motor parameters in-line with parameter values programmed by an operator. Speed rating of the MDD071A-N-040-N2S-095GA1 motor is 4000 RPM. The continuous torque at standstill is 2.2 Nm. The continuous current t standstill is 5 Amps. The theoretic maximum torque is 6.9 Nm. The maximum current rating is 22.6 Amps. Moment of inertia of the motor shaft is 0.00044 kg m². The torque constant at 20 degrees Celsius is 0.44 Nm/A. The motor winding resistance at 20 degrees Celsius is 2.61 Ohms. The motor winding inductance is 11.5 millihenry.

Thermal time constant of the MDD071A-N-040-N2S-095GA1 motor is 45 minutes. The mas of the motor is 6.5 kilograms. Cooling methods for the motor include surface cooling and natural convection. The shaft on the motor is plain. If required, operators can also order a shaft with keyway. The motor centering diameter is 95 millimeters. The power connection is located on side A. Sealed cable connectors contribute to the IP65 protection rating for the servo motor. The blocking brake on the servo motor works according to the electrically actuated release principle. Holding torque of the brake is 3 Nm. The permissible ambient temperature with rated output is 0 to 45 degrees Celsius. The permissible ambient temperature with derated output is 45 to 55 degrees Celsius. The permitted maximum installation elevation is 1000 meters above sea level. The motor housing coat is black prime coat (RAL 9005).
