Product Description:
The MKE098B-047-CG1-BUNN is a servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for use in potentially explosive areas, and the housing meets UL/CSA requirements for that type of installation. The motor operates in ambient temperatures from 0 to +40 °C. Power and feedback lines enter through a terminal box on the B-side, which helps keep wiring clear of rotating parts. A plain shaft with a frontal centering hole and a DIN 332 DS thread is protected by a shaft seal, and an integrated holding brake secures the load when power is removed.
At standstill, the motor can deliver 12.0 Nm of continuous torque with a corresponding current of 9.8 A, which supports accurate static positioning. During acceleration, it can draw up to 44.3 A (rms) and produce a peak torque of 43.5 Nm for short-term load changes. Maximum speed reaches 4500 rpm, while a voltage constant of 91.0 V per 1000 rpm and a discharge capacity of 6.7 nF help characterize its electrical behavior at the drive terminals. The optical multiturn Hiperface encoder, model M1 with 128 increments per revolution, supplies absolute position data for closed-loop control. Winding code 047, a resistance of 8.400 Ω, insulation class 155 F, and a sound pressure level of 61.8 dB[A] describe the motor’s steady-state electrical and operating characteristics.
Torque output changes in proportion to current through a constant of 1.41 Nm/A, which allows predictable torque production from the commanded current. The winding inductivity of 1.20 mH affects how quickly phase current can respond during rapid torque changes. A rotor moment of inertia of 0.00430 kgm² supports responsive acceleration and deceleration on dynamic axes. During shutdown, the integrated brake applies 11 Nm to hold the load in place. The total mass is 18.0 kg, giving the motor a solid mechanical presence for repeated motion cycles without making the unit unusually large for its performance range.
