Product Description

The Bosch MKD112B-073-GG1-BN is an AC servo motor. It is designed for industrial applications and is compatible with intelligent digital controllers from Rexroth Indramat. It belongs to the MKD product line which includes motors that have rated speeds ranging from 2500 to 9000 RPM and rated torque ranging from 1 Nm to 75 Nm. MKD motors are available in four different frame sizes which are the MKD_A, MKD_B, MKD_C and MKD_D. MKD motors are also available in surface cooled or air cooled versions. The MKD112B-073-GG1-BN is a synchronous motor with 28 Nm rated continuous torque at standstill. Flange size of the MKD112B-073-GG1-BN is 192 millimeters. The centering diameter of the motor is 130 millimeters. The motor shaft is plain with sealing ring. The motor is balanced using a featherkey which is not included with the motor.

Resolver based feedback and a holding brake are available on the motor. The 22 Nm rated holding brake on the MKD112B-073-GG1-BN weighs 1.1 kilograms. Clamping delay and release delay for the holding brake are 25 milliseconds and 50 milliseconds respectively. The brake requires 24 Volts DC input and consumes 0.71 Amps current. The holding brakes operates according the electric release principle. When de-energized, a magnetic force acts on the armature disk causing the brake to close. When 24 Volts DC is applied, the magnetic field is compensated and the bake opens. Output direction of the power connector on the MKD112B-073-GG1-BN is side B. Ambient conditions for motor operation which are recommended by Bosch include 0 to 40 degrees Celsius temperature and maximum setup height of 3300 feet. The motor output derates when operated outside these recommended conditions. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
