R911273949
Produced by Bosch Rexroth Indramat, R911273949 (MHD093C-035-NG0-BN) is a premium-grade synchronous servo motor designed to perform exceptionally well. The motor where natural convective heat dissipation is used, functions under two over-temperature conditions, 60K and 100K. During these conditions, it provides a steady torque of 12 Nm and 14 Nm, along with a seamless current of 10.2 Amps and 11.9 Amps respectively. By applying surface cooling techniques in 60/100 K over-temperature situations, it exhibits superior output with a consistent torque of 18 Nm while supplying a persistent current of 15.3 Amps. The peak current of this motor is rated at 45.9 Amps with a torque constant at a 20°C environment being 1.29 Nm/A. The motor features four pole pairs, and to ensure this level of performance, it possesses 1.75 Ohms winding resistance at 20°C.
When operating under a 60K over-temperature setting with natural convection, the motor boasts a rated speed of 3000 RPM, producing a torque of 6.1 Nm, enforcing 3.7 Amps current with 2.2 kilowatts of power at a rated voltage of 347 Volts. Conversely, under a 100K over-temperature scenario, the motor provides an impressing power of 3.6 kilowatts at a rated voltage of 357 Volts, maintaining a torque of 10 Nm, and a 6 Amps current. Cooling the motor surface during these temperatures increases the rated motor data. The R911273949 (MHD093C-035-NG0-BN) is not equipped with a holding brake and supports digital servo feedback. The power connector is ideally located on side B, and a plain shaft, inclusive of a seal, ensures smooth operation.
