Product Description:

The MKE098B-047-NG1-BENN is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MKE Synchronous Motors series. Designed as a servo motor for potentially explosive areas, it uses an ATEX-approved housing so it can be installed in Zone-rated production lines without extra mechanical barriers. The device accepts power from a compatible drive controller and converts it into controlled rotation for mixers, palletizers, and similar automation axes that must meet hazardous-location rules while keeping size and wiring practices consistent with standard factory motors.

With a winding temperature rise of 60 K, the motor can deliver a continuous torque of 12.0 Nm while drawing 9.8 A at standstill, providing steady force for low-speed holding or indexing moves. During transient events such as acceleration or impact loading, the shaft can reach a peak torque of 43.5 Nm, and the rotor can spin up to 4500 rpm without exceeding mechanical limits. Rated ambient conditions span 0 to +40 °C, so no derating is required in most production halls. The electromagnetic circuit yields a torque constant of 1.41 Nm/A, so each ampere supplied by the drive produces a predictable amount of torque. Additional electrical data include winding code 047, an inductance of 1.20 mH, a resistance of 8.400 Ω, and a voltage constant of 91.0 V/1000 rpm for matching the motor to compatible inverter output stages.

An integrated holding brake supplies 11 Nm of static torque to secure vertical loads when the system is de-energized. Dynamic behavior is influenced by a rotor inertia of 0.00430 kgm², which supports quick speed changes without excessive drive current. The housing weighs 18.0 kg excluding the brake, and it uses a plain shaft with a frontal centering hole, a DIN 332 DS thread, and a shaft seal to help limit ingress. A terminal box on the B-side streamlines field wiring, and a sound pressure level of 61.8 dB[A] keeps operating noise within typical plant conditions.
