Product Description:

The MKE098B-058-AP0-BENN is a servo motor produced by Bosch Rexroth Indramat and assigned to the MKE Synchronous Motors series. Designed for potentially explosive areas, the motor supplies regulated rotary motion for automated conveyors, mixers, and precision stages used in chemical processing and paint finishing lines. Its synchronous design allows the connected drive to control speed and position accurately during repeatable machine cycles under changing load conditions.

It delivers a continuous standstill torque of 12.0 Nm when the windings are stabilized at 60 K above ambient, and it draws 12.4 A under the same condition. For transient load surges, the drive can accept a maximum phase current of 55.9 A, enabling peak torque up to 43.5 Nm. The mechanical limit speed is 5000 rpm, giving a wide velocity range for variable-speed tasks. The ATEX-compliant housing allows deployment between 0 °C and +40 °C without derating. Power and feedback cables exit on the B-side through a sealed terminal box, and the motor has no integrated holding brake, so stationary loads require external holding. An optical single-turn Hiperface encoder with 128 increments, model S1, supplies absolute rotor position to the servo drive.

With a torque constant of 1.09 Nm/A, commanded current produces predictable torque output. The low rotor moment of inertia of 0.00430 kgm² supports fast acceleration while still matching loads through the 058 winding, whose 0.740 mH inductance and 5.80 ohm resistance establish the motor’s electrical response. An internal discharge capacity of 6.7 nF limits common-mode noise returned to the drive. The keyed shaft follows DIN 6885 and includes a shaft seal for use in dusty or light-spray areas. Acoustic emissions stay at 61.8 dB[A] (±3), and Class F insulation supports elevated winding temperatures. The motor weighs 18.0 kg, which matters when it is installed on gantry or robot arm axes.
