Product Description:
The MKE098B-058-CP0-BUNN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for use in potentially explosive industrial zones where precise rotary actuation must comply with UL and CSA housing requirements. The design uses a terminal-box connection on the B-side and a shaft with a DIN 6885 keyway, enabling direct coupling to gear stages or drive shafts. This model is supplied without a holding brake, so external mechanical retention must be provided when the axis must remain motionless during power loss. Its hazardous-area construction also suits process equipment that requires accurate motion with a familiar industrial shaft and connection layout.
At standstill, and with a 60 K winding temperature rise, the motor can continuously deliver 12.0 Nm while drawing 12.4 A. The torque constant of 1.09 Nm/A links commanded drive current to output torque, which helps keep current scaling straightforward. For dynamic peaks such as acceleration or load impact, the unit permits up to 43.5 Nm, and the mechanical design supports operating speeds as high as 5000 rpm. This operating range makes the motor suitable for conveyor, spindle, or mixing duties that require both strong startup torque and stable motion during continuous running.
The motor is rated to operate in ambient temperatures from 0 to +40 °C, which aligns with typical industrial cabinet and machine conditions. A back-EMF constant of 70.0 V/min⁻¹ assists the inverter with rotor estimation and DC bus voltage selection. With a rotor inertia of 0.00430 kgm², the axis balances quick response with stable speed regulation, and the total mass of 18.0 kg helps resist vibration during operation. Insulation class 155 (F) supports elevated winding temperatures. A shaft seal, 0.740 mH phase inductance, 5.80 Ω resistance, and 6.7 nF discharge capacity influence current ripple, conducted EMI, and the motor's electrical behavior at the drive.
