Product Description:
The MKE118D-012-DP3-KE4 is a servo motor for potentially explosive areas produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Its ATEX-certified housing and IP65 sealing make it suitable for dusty or wet production zones, and it converts regulated drive current into precise rotary motion for heavy positioning tasks. The connection direction is upward, which supports top-entry cable routing on enclosed machinery. This type of motor is commonly used on automated axes that require accurate speed regulation and repeatable positioning in hazardous areas.
At a 60 K stator rise, the motor delivers a continuous torque of 48.0 Nm while drawing 13.0 A for sustained duty. For transient moves, it can reach 187.0 Nm and accept a peak current of 58.5 A, enabling shaft speeds up to 2000 rpm. Winding code 012 has a resistance of 0.98 Ω and an inductance of 15.000 mH, which affects current response. The optical multi-turn EnDat 2.1 encoder, model M2, provides absolute feedback through a terminal box located on the top of the frame. Cable entries accept diameters from 13.0 mm to 16.0 mm. The motor operates in ambient temperatures from 0 °C to +40 °C, and its sound pressure level is 61.1 dB(A) ±3 under nominal load.
A torque constant of 4.29 Nm/A links phase current to output torque, and the associated back-EMF constant is 263.5 V/1000 rpm. With a rotor inertia of 0.03620 kgm², the axis balances dynamic response and load damping, while a holding brake rated at 70 Nm secures vertical masses during shutdown. The motor has a shaft with a DIN 6885 keyway and a fitted shaft seal, which supports positive torque transfer to couplings or pulleys. It also uses insulation class 155 F windings and has a mass of 65.0 kg without the brake. The ATEX housing and terminal-box layout help limit surface temperature and capacitive coupling in hazardous areas.
