Product Description:

The MKE098B-047-PG0-BUNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for motion control in potentially explosive environments where regulated speed and positioning are required. The unit follows UL and CSA housing standards, uses a plain shaft with a frontal centering hole, and routes its power and feedback leads through a terminal box on the B-side of the frame, allowing straightforward conduit entry inside hazardous-area enclosures.

Under steady thermal conditions, the motor delivers a continuous stall torque of 12.0 Nm while drawing 9.8 A. These values indicate the load the drive can hold continuously without exceeding the 60 K winding temperature rise. For short-duty bursts, it can supply up to 43.5 Nm, and this peak value must remain within the matching inverter current limit of 44.3 A. Dynamic tasks benefit from a top mechanical speed of 4500 rpm, so high-cycle pick-and-place or spindle applications can run without gear multiplication. The F-class insulation system tolerates winding temperatures up to 155 °C, and a shaft seal is fitted to limit gas or dust ingress at the coupling interface. Because the motor is supplied without a holding brake, installations that need static load retention must rely on external clamping or drive torque.

The torque and current capabilities are supported by a conversion efficiency of 1.41 Nm/A at 20 °C, allowing predictable control loop tuning. Acceleration behavior is influenced by the rotor inertia of 0.00430 kgm², and this moderate value helps the axis change speed quickly without demanding excessive drive power. Operation is permitted at ambient temperatures from 0 to +40 °C, permitting placement in standard factory zones without auxiliary cooling. With a mass of 18.0 kg, the motor can be mounted on linear slides or machine frames without heavy support brackets. Its rated sound pressure level is 61.8 dB[A], which supports use in general industrial equipment.
