Product Description
The MDD090C-N-040-N2L-110GA1 is a Bosch MDD series servo motor. Its housing has a standard design. The cooling methods that operators can use include surface cooling and natural convection. Surface cooling requires a blower to force air across the surface of the operating motor. Performance specifications with surface cooling include 14.6 Nm output torque at standstill, 34.3 continuous current at standstill and 45 minutes thermal time constant. Performance specifications with natural convection include 10.4 Nm output torque at standstill, 24.4 continuous current at standstill and 60 minutes thermal time constant. The theoretical maximum torque of the motor is 58.6 Nm and the maximum current is 145.7 Amps. The moment of inertia of the motor rotor is 0.0053 kg m2. The torque constant at 20 degrees Celsius is 0.43 Nm/A. The motor windings resistance is 0.29 Ohms at 20 degrees Celsius.
The motor windings inductance is 1.6 millihenry. Shipping weight of the MDD090C-N-040-N2L-110GA1 motor is 23 kilograms. The motor is equipped with a blocking brake rated for 6.5 Nm holding torque. Nominal voltage rating of the brake is 24 Volts DC. Current draw of the brake is 0.5 Amps. The brake requires 60 milliseconds after application of the release signal to release the shaft. The brake requires 20 milliseconds to clamp down on the shaft to prevent it from rotating. Weight of the blocking brake on the motor is 0.5 kilograms. The motor power socket is located on side A of the housing. The motor has a plain output shaft. Speed rating of the MDD090C-N-040-N2L-110GA1 is 4000 RPM. The motor supports digital servo feedback. The housing of the MDD090C-N-040-N2L-110GA1 motor is painted black. An additional 40-micrometer layer of paint can be applied on top of the black prime coat.
