      Variable-frequency Water Pumps
      Leveraging the full-chain synergy of its IDM model, crmicro delivers highly reliable variable-frequency energy-saving solutions that enable our clients to optimize equipment energy efficiency, reduce operating costs, and improve overall productivity.
      Solution Overview
      Targeting the electronic control system for variable-frequency water pumps, the solution covers the full chain: motor variable-frequency drive, regulated power supply, signal isolation, and CAN communication. Relying on power devices (IGBT/SiC MOSFET/SiC diode/IPM), dedicated motor MCUs, linear regulators, isolation optocouplers and RS-485 communication ICs, it enables smooth speed regulation and intelligent speed control with patented small-electrolytic capacitor control technology, improving operating energy efficiency, stability and intelligent interaction capability.
      Solution Advantages
      • Energy saving & high efficiency lead to low operating cost
      • Variable-frequency control extends motor life
      • Precise algorithm control delivers strong system stability
      • Not sensitive to motor parameter variations, adapting to complex operating conditions
      • Low noise at low speeds, eco-friendly and comfortable
