The R911337917 (MKE118B-058-AG0-KE4) is a Bosch Rexroth MKE permanent-magnet servo motor, designed with an ATEX certified housing for use in potentially explosive areas. The motor has a maximum speed of 4500 RPM, a thermal time constant of 90 minutes, and continuous torque and current ratings of 28 Nm and 28.4 Amps respectively. The motor's peak torque and current ratings stand at 102 Nm and 127.6 Amps respectively, with a motor torque constant and voltage constant of 1.15 Nm/A and 70 V/RPM at 20 degrees Celsius. The motor comes equipped with a single-turn optical encoder with an EnDat 2.1 interface, offering 2048 encoder lines and an accuracy of ±20 angular seconds. The R911337917 (MKE118B-058-AG0-KE4) features a smooth, sealed shaft to protect the bearings and prevent oil leakage. It doesn't include a holding brake but has a lifetime-greased bearing for maintenance-free operation.
