The Rexroth R911312436 (MKD090B-035-GG2-KN) is a synchronous AC motor from the Indramat MKD series. It has a flange size of 140 millimeters, motor length of B equivalent to 12 Nm, a centering diameter of 110 millimeters, and uses natural convection for cooling. The motor winding has a code of 035, resistance of 1.88 Ohms, and an inductance of 15.5 millihenry. It has 4 pole pairs, uses a resolver for feedback, and has a plain shaft with a sealing ring. The motor shaft's maximum speed is 5000 RPM, while its rated speed is 3000 RPM. The R911312436 (MKD090B-035-GG2-KN) operates with 49.5 Amps peak current, 1.22 Nm/A torque constant, and 111 Volts per 1000 RPM voltage constant. Its weight is 14 kilograms, the thermal time constant is 60 minutes, and it delivers a theoretical maximum torque of 43.5 Nm. This motor is designed to be controlled by Rexroth's HDS and HDD drive controllers. It is globally available with a one-year warranty from Indramat USA.
