Product Description:

The MKE037B-144-AP0-RUNN is a servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for potentially explosive areas, it provides closed-loop rotary motion where flammable gases or dust may be present. By combining an optical feedback device with a flameproof housing, the unit serves as a drive element in hazardous-zone conveyors, mixers, and positioning systems that rely on precise speed and torque control.

The housing carries an ingress rating of IP 65, so airborne dust and water jets cannot reach the internal stator or encoder. Continuous duty is permitted from 0 to +40 °C, helping the winding code 144 remain thermally stable in ordinary plant climates. Class-F insulation, noted as 155 (F), increases allowable coil temperature before varnish breakdown. Position data come from an optical encoder that provides 128 discrete counts per revolution and uses the Singleturn Hiperface protocol; this combination supports digital drive controllers that require absolute position at power-up without a secondary homing routine. These features, along with a keyed shaft and a permanent-magnet rotor, support the motor’s dynamic accuracy and overload capacity.

Cabling enters from the Right through a sealed terminal box, simplifying wiring in compact enclosures. The cast-aluminum body conforms to UL/CSA construction rules for North American hazardous locations, and a shaft seal is fitted to maintain overpressure inside the motor while blocking external contaminant ingress. Torque is transferred through a key that conforms to DIN 6885, which helps prevent slip during startup surges. Because the unit is supplied without a holding brake, any static load must be secured by the drive or by an external mechanical lock, a common arrangement on fan, pump, and agitator axes where coast-down is acceptable.
