Centrifugal ePump

Definition & performance

A centrifugal ePump is an integrated mechatronic system combining a hydraulic centrifugal pump with a BLDC motor and embedded electronics (driver + control). The rotating impeller accelerates the fluid radially, converting velocity into pressure, while electronic commutation enables precise speed control and demand-based operation. Performance is defined by the Q–H curve (flow vs head), optimized through closed-loop motor control and system-level integration.

​

Value proposition (MMT)

  • Integrated system (motor + pump + electronics) → compact, plug-and-play

  • On-demand control via inverter (PWM / FOC) → optimized efficiency

  • Low NVH system (motor + hydraulics) → key differentiator

  • High efficiency vs mechanical pumps → reduced energy consumption

  • Scalable platform architectures (12–48V EV cooling loops)

  • Enables smart thermal management (sensing + control integration)

  • Wet rotor architecture possible→ leakage-free operation and enhanced reliability

  • Rare-Earth free design (RE/HRE)
