R911281213
The R911281213 (MHD112C-058-PG3-BN) is a high-quality, synchronous motor crafted by Bosch Rexroth Indramat, a globally recognized name in the realm of industrial technology components. It sets a high industry standard, integrating robust features such as free convection and surface cooling mechanisms for temperature regulation. Accompanied by a thermal time constant of 40 to 90 minutes, the unit weighs 45 kilograms and houses a shaft with key and sealing ring. Further to this, the motor is protected with a black paint finish, sustaining operability within temperatures of 0 to 40 degrees Celsius at heights less than 1000 meters above sea level.
This model entails a secure 3.8-kilogram holding brake, providing a holding torque of 70 Nm, a rated current of 1.29 A, and a 24-volt rated voltage. The motor offers a winding inductivity of 1.5 mH and a torque constant of 0.8 Nm/A, both accurate with the assistance of a multiturn absolute encoder for positioning and speed determination. The R911281213 (MHD112C-058-PG3-BN) also boasts a maximum torque of 148 Nm and a peak current consumption of 239 A. It has a moment of inertia of 273 x 10-4 kgm2 along with a maximum rotational speed of 4500 RPM, making it remarkably efficient. It is to be ensured that the motor is safeguarded from environmental factors exceeding its protection degree of IP65 and insulation class of F.
