Product Description:
The MKE098B-047-KG0-BUNN is a servo motor for potentially explosive areas manufactured by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Its flame-proof housing meets UL and CSA requirements, and the power and feedback leads exit on side B through a terminal box that simplifies armored cable terminations. The motor uses winding code 047 and is supplied without a holding brake, so any required static locking must be provided by the machine. A plain shaft with a frontal centering hole and a DIN 332 DS thread is fitted with a shaft seal to help limit vapor ingress in hazardous zones.
At a 60 K winding rise, the unit produces continuous torque of 12.0 Nm while drawing 9.8 A, and headroom is available up to a maximum torque of 43.5 Nm during acceleration. The rotor can reach 4500 rpm, and the winding combines 1.20 mH inductance with 8.400 Ω resistance to help keep current ripple low. A torque constant of 1.41 Nm/A links drive current to shaft output, and the motor also has a back-EMF constant of 91.0 V per 1000 rpm during regeneration. Under transient load spikes, the inverter may deliver up to 44.3 A RMS without exceeding the stator thermal limit of the class F insulation. The 6.7 nF discharge capacitance helps bleed static charge away from the laminated core, reducing the risk of capacitive discharge in dust-laden atmospheres.
Total mass is 18.0 kg, giving the frame enough thermal mass to stay within the allowed ambient range of 0 to +40 °C during continuous duty. An insulation class 155 (F) rating permits winding temperatures well above ambient without premature varnish aging. Sound pressure is listed at 61.8 dB[A] at a distance of one meter, and the sealed output end helps limit the movement of vapors around the shaft area. The terminal box on side B keeps field wiring accessible without requiring the main housing to be opened.
