Product Description:
The MKE098B-058-CG1-AUNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for servo applications in potentially explosive areas, where controlled rotary motion is needed for actuators, conveyors, and mixers operating in hazardous zones. The motor combines a UL/CSA-compliant housing, an integrated holding brake, and optical multi-turn feedback so control systems can position loads accurately while meeting industrial safety requirements.
At a 60 K winding rise, the motor delivers a continuous torque of 12.0 Nm while drawing a standstill current of 12.4 A. The 058 winding variant uses a resistance of 5.80 Ω, an inductance of 0.740 mH, and a capacitance of 6.7 nF, which gives the drive consistent electrical values for current control. A torque constant of 1.09 Nm/A relates electrical input to mechanical output, and the optical multi-turn Hiperface encoder with model M1 and 128 increments transfers absolute rotor position to the controller. For short-duty operation, the shaft can produce up to 43.5 Nm and reach speeds of 5000 rpm. Insulation class 155 F supports the thermal design, and ambient operation from 0 °C to 40 °C keeps acoustic emission at 61.8 dB(A).
Power and feedback cables enter from the A-side through a terminal box, which keeps the connection point contained and easy to route within the machine layout. The motor uses a plain shaft with a frontal centering hole and a DIN 332 DS thread, and a shaft seal helps prevent ingress at the output end. A holding brake provides 11 Nm of static torque, and the drive can supply up to 55.9 A rms for rapid acceleration against a rotor inertia of 0.00430 kg·m². The motor weighs 18.0 kg without the brake, allowing rigid mounting in either vertical or horizontal orientations.
