MKE098B-047-CP0-BE0N
MKE Synchronous Motors
The MKE098B-047-CP0-BE0N is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. Designed as a drive component for potentially explosive atmospheres, the unit converts electrical energy from a compatible controller into controlled rotary motion for pumps, mixers, or conveyor axes that must meet ATEX requirements. It ships in a flame-proof housing with a B-side terminal box and uses an optical multiturn absolute Hiperface encoder to relay position data to the drive, allowing closed-loop operation in Zone-rated installations.
At 60 K winding temperature rise, the motor delivers a continuous standstill torque of 12.0 Nm, providing enough holding capability for static loads without overheating. When short-term acceleration is required, the drive can reach a peak of 43.5 Nm, so motion planners can size gear ratios for rapid indexing without exceeding the permissible stress on the shaft with DIN 6885 keyway. A top speed of 4500 min⁻¹ supports high surface velocities while the winding can accept up to 44.3 A RMS, a current limit that the connected inverter must respect to avoid demagnetization. With a torque constant of 1.41 Nm/A, the torque output scales predictably with phase current, simplifying controller gain settings during commissioning.
Mechanical dynamics are influenced by a rotor inertia of 0.00430 kg·m², which moderates acceleration profiles so that the electrical limits stated above can be used without inducing excessive oscillation in lightly loaded axes. The enclosure weighs 18.0 kg, supporting stable mounting on machinery frames and contributing to low structural resonance. Safe operation is specified for ambient temperatures from 0…+40 °C; within this range the F-class insulation system rated at 155 (F) maintains dielectric strength, ensuring that the motor can exploit the current, torque, and speed capabilities cited earlier under typical plant conditions.
