Product Description:

The MKE098B-047-GP0-BUNN is a servo motor built by Bosch Rexroth Indramat and assigned to the MKE Synchronous Motors series. As a servo motor for hazardous locations, it is used in automation cells that must meet hazardous-location directives while still delivering closed-loop position control. In operation, the unit works with a drive controller to rotate machine shafts, conveyors, or actuators with the precise speed and torque regulation required in material handling, packaging, or process equipment.

Its thermal standstill rating provides a continuous torque of 12.0 Nm while drawing a continuous current of 9.8 A; these values show the load it can sustain indefinitely at a 60 K winding temperature rise. During short-duty peaks, the motor can reach a maximum torque of 43.5 Nm, and the drive may deliver up to 44.3 A RMS to help the axis accelerate or overcome transient process forces. Mechanical speed capability reaches 4500 rpm, so the driven shaft and gearing must keep the application within that limit. The motor operates without a holding brake, so static holding torque must be provided externally. The ambient temperature range of 0 to +40 °C covers typical factory or control-room conditions without derating.

The electromagnetic design uses winding code 047 with a torque constant of 1.41 Nm/A, so the controller can estimate torque output directly from commanded current. Rotor dynamics are influenced by a moment of inertia of 0.00430 kgm², which supports responsive acceleration without excessive overshoot. A phase inductance of 1.20 mH and a phase resistance of 8.400 Ohm affect current rise time and copper losses, while the 6.7 nF discharge capacity helps damp voltage transients at the terminals. Sound pressure is limited to 61.8 ±3 dB[A], the housing weighs 18 kg, and the motor uses a UL/CSA-listed F-class insulation system, terminal box connections on side B, a shaft with a DIN 6885 keyway, a shaft seal, and a back-EMF constant of 91 V per 1000 rpm.
