Product Description:
The MKE098B-058-CP0-AUNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed as a servo motor for potentially explosive areas, it provides controlled rotary motion in hazardous-area automation where vapor or dust ignition must be avoided. The housing follows UL/CSA standards, which supports use in regulated industrial environments. Power is routed through a terminal box on the A-side, and an optical multi-turn absolute Hiperface encoder with M1 format and 128 increments supplies position data to the drive so closed-loop speed and position control can be maintained during changing load conditions.
At a 60 K winding temperature rise, the motor sustains 12.0 Nm of continuous torque and requires a continuous standstill current of 12.4 A. These values help match the motor to an inverter so the axis can hold its load without overheating during normal operation. For short overload periods, the drive may deliver up to 55.9 A, allowing peak torque of 43.5 Nm during acceleration or startup. F-class insulation supports a 155 °C winding limit, the permitted ambient range is 0 to +40 °C, and the combination of 0.740 mH inductance with 5.80 Ω phase resistance affects current response while the shaft seal helps keep oil away from the encoder.
A top speed of 5000 min⁻¹ and a rotor inertia of 0.00430 kg·m² give the motor a balance of responsiveness and stability for applications that cycle quickly but must avoid overshoot. The torque constant of 1.09 Nm/A reflects the motor’s magnetic efficiency, while the back-EMF voltage constant of 70.0 V/min⁻¹ helps the drive anticipate generated voltage during dynamic braking and deceleration. With a mass of 18.0 kg, the unit can be mounted on moderate-size gearheads without requiring extra external support in many machine layouts. A DIN 6885 keyed shaft provides positive mechanical coupling under reversing loads, which is useful where repeated direction changes place added stress on the shaft connection.
