Product Description

The MKD112B-048-GG2-BN is a motor designed and manufactured by Bosch Rexroth. The characteristic motor speed is 3500 RPM. Bosch provides motor ratings for 60K and 100K overtemperature conditions. For the 60K condition, the continuous torque and continuous current at standstill for the MKD112B-048-GG2-BN are 28 Nm and 35.6 Amps respectively. For the 100K conditions, the continuous torque and continuous current at standstill for the motor are 33 Nm and 43.5 Amps respectively. Torque constant and voltage constant for the MKD112B-048- GG2-BN at 20 degrees Celsius ambient temperature are 0.88 Nm/A and 80 V/1000 RPM respectively. Resistance of the motor winding at 20 degrees Celsius is 0.22 ohms. Feedback is supported on the motor through an integrated resolver. The main motor shaft is plain and features a keyway.

Connector for motor power and encoder is located on side B of the MKD112B-048-GG2-BN motor. A holding brake rated for 32 Nm holding torque is provided on the motor. Mechanical specifications for the MKD112B-048-GG2-BN include 192 millimeters flange size, theoretical maximum torque at 102 Nm, thermal time constant of 40 minutes, 4500 RPM maximum motor speed and IP 65 rated motor housing. A range of motor speeds are possible: Bosch has provided detailed torque speed curves in the motor documentation for a variety of operating conditions. Minimum recommended wire size to be used for the motor power supply is 6 mm². The motor speed can be limited be mechanical causes such as bearing stress and centrifugal forces and by electrical causes such as DC link voltage. If the motor is operated outside the recommended ambient conditions, then the load factors should be considered. Operating the motor outside recommended ambient conditions can also lead to motor damage. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
