R911321289
The R911321289 (MKE037B-144-AP0-BENN), a product of Bosch Rexroth Indramat, belongs to the MKE series of high dynamics servos. Notably, it possesses a winding code of 144, indicating its electric motor output, a motor frame size of 37, and a motor length of B. The model is absent a holding brake. This brushless design servo is renowned for its maintenance-free operation, high performance, reliability, and high overload capacity. Further distinguishing features include its B-side electrical connection and adaptability for continuous start-stop operations. It's worth noting that this 2.5 kg model is crafted to suit installation in ATEX standard housing.
The R911321289 (MKE037B-144-AP0-BENN) incorporates an electronic commutation system and uses an optical single-turn Hiperface encoder with 128 increments for precise control of speed and position. Its encoder has a maximum speed of 12000 rpm, runs on a voltage supply of 7 to 12 volts, and has max. current consumption of 60 milliamperes. The unit also features a sound pressure level of 64.3 dB(A) ±3, a thermal time constant of 15 minutes, and a maximum velocity of 9000 rpm. It has a torque constant of 0.30 Nm/A and a voltage constant of 18.2 V/min-1 at 20 oC. The unit's operating temperature range is 0 to 40 degrees C, and it aligns with an Ingress Protection rating of 65 and the insulation category 155 as per DIN EN 60034-1 standards.
