M4Q045-EF01-75 ebmpapst 230VAC Q-Motor for Refrigeration

Description

The ebmpapst M4Q045-EF01-75 is a high-torque single-phase AC shaded-pole motor from the specialized Q-motor series, engineered for heavy-duty service in commercial refrigeration and industrial ventilation. Driven by the M4Q045-EF motor core, this unit delivers a significant power output of 34 W with a nominal input of 110 W at 50 Hz, providing the necessary torque (24 Ncm) to drive large axial fan blades. The robust design features a die-cast aluminum bearing shield and maintenance-free calotte bearings, ensuring stable S1 continuous operation even in low-temperature environments down to -30 °C. For enhanced safety, the motor is equipped with an internally connected thermal overload protector (TOP) and carries a Class B insulation rating. With its versatile mounting capabilities and high starting torque, the M4Q045-EF01-75 is the definitive solution for demanding evaporator and condenser applications in the global refrigeration industry.
