Product Overview

With its recent release of the new CAplus motor, Nidec Conversion has expanded its family of Totally Enclosed Fan Cooled (TEFC) motors offering even better efficiency and reliability. Designed for applications with quadratic torque loads like centrifugal pumps, compressors and fans, the CAplus is a popular industrial solution for end users, engineering firms and OEMs due to its very low vibration and noise level performance.

Desalination Plant

Specifically designed for aggressive environments & heavy duty

CAplus motors offer global functionality that meet or exceed National Electrical Manufacturers Association (NEMA) or International Electrotechnical Commission (IEC) standards. These products are expected to be in great demand by the oil & gas, water treatment and industrial process industries because their innovative design offers very high efficiency, power factor and competitive cost. The rugged, fabricated frames motors undergo our standard aggressive-environment painting cycle making them well suited to withstand abrasive atmospheres.

One of the highest efficiency on the market today

The CAplus delivers high performance in terms of power factor and efficiency that puts the machine at the top of its class. Its innovative cooling system dissipates heat more effectively to achieve greater efficiency (more than 97% with a power factor of 0.89), which can translate into savings up to $ 12.000 per year. The motor has a fabricated steel frame offering optimum performance in terms of vibration and mechanical strength.

Circular Economy Committed

The CAplus has been designed with the environment in mind: built using state-of the-art technology, it achieves maximum performance with minimum environmental impact.

  • Highest kW/kg means maximum performance is achieved from the material used
  • Optimized cooling, minimal insulation materials
  • More than 95% of the material used can be recycled at the end of motor’s life

Innovative cooling system

Our new CAplus series uses an innovative cooling shroud and tubing system to increase the performance and extend the life of the motor.
