Product Description:

The MKE047B-144-CP1-BENN is a servo motor for potentially explosive areas produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It functions as the rotary actuator in automation zones where combustible gases or dust may be present, delivering closed-loop motion while supporting hazardous-area requirements. When paired with a suitable inverter, it can drive process valves, indexing tables, or packaging spindles that need precise speed and torque control. The design is intended for applications that require both motion accuracy and operation in classified plant environments.

The motor housing carries ATEX conformity, allowing installation in zone-rated plants. Thermal endurance comes from an insulation system rated to 155 (F), which supports high winding temperatures during normal operation. A rotor with 4 pole pairs sets the synchronous electrical relationship and helps smooth low-speed torque. The holding brake provides 2.2 Nm of static torque to keep the load in place when power is removed, and a shaft seal helps keep oil or dust away from the bearing cavity. Position data are supplied by an optical multiturn Hiperface encoder with 128 counts per revolution, while winding code 144 matches the electrical characteristics expected by compatible Rexroth drives.

Cable termination is handled through a terminal box mounted on the motor's B-side, which helps with cable routing in compact cabinets. The encoder option is M1, so absolute position is available immediately after power-up and a homing routine is not required. Drive torque is transmitted through a shaft with a DIN 6885 keyway, which gives positive engagement to pulleys or couplings and helps prevent slip during reversals. This arrangement supports secure power connections and a stable mechanical interface for keyed transmission components.
