Product Description:
The MKE098B-058-CP1-AUNN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for potentially explosive areas and converts drive controller commands into regulated rotary motion for conveyors, mixers, and packaging stations in hazardous zones. Its flame-tight housing, UL/CSA listing, and integrated optical feedback support precise speed and position control in industrial automation. A terminal box on the A-side simplifies field wiring in explosion-rated enclosures.
The motor uses winding code 058 with a resistance of 5.80 Ω at 20 °C and an inductance of 0.740 mH, which affect electrical response and heat rise. At a 60 K winding temperature increase, it supplies a continuous torque of 12.0 Nm while drawing 12.4 A; under dynamic demand, the drive may deliver 55.9 A to reach a peak torque of 43.5 Nm. Shaft speed is adjustable up to 5000 rpm, and the torque constant of 1.09 Nm/A lets the controller calculate torque directly from phase current. Position data are reported by an M1 optical multi-turn absolute Hiperface encoder that yields 128 increments per revolution. Wiring enters a sealed terminal box on the A-side, and the output shaft uses a DIN 6885 keyway with a shaft seal. The sound pressure level is 61.8 dB[A] ±3, the discharge capacitance for EMC is 6.7 nF, the insulation class is 155 F, and the motor operates between 0 °C and 40 °C.
A rotor inertia of 0.00430 kg·m² moderates acceleration and helps limit overshoot on mid-mass mechanisms. The integrated brake holds the shaft with 11 Nm when power is removed, which helps prevent drift on vertical axes. During high-speed operation, the back-EMF constant is 70.0 V/min⁻¹. The cast frame weighs 18.0 kg, which adds thermal mass and helps damp vibration during continuous-duty use.
