Electric Motor Manufacturers

Your motor’s performance is defined by its drive. We engineer it to match.

If you manufacture electric motors — BLDC, SynRM, DC, AC induction — the electronic drive is not an accessory. It is what unlocks your motor’s efficiency, controls its behavior under load, and determines how your customers experience your product. A generic inverter cannot do that. A purpose-built drive can. KELD has been designing and manufacturing custom motor drives for motor OEMs since 1997. We understand that every motor family has a unique control signature, and we engineer drives that are matched to your specific rotor geometry, winding configuration, and application requirements.

TYPICAL CHALLENGES WE SOLVE

  • Developing drive electronics that extract maximum efficiency from your specific motor design — not a generic control algorithm applied to a generic motor.
  • Matching your motor to application-specific requirements: torque profiles, speed ranges, thermal constraints, and noise targets.
  • Ensuring the motor-drive combination meets efficiency and safety certifications across multiple markets (CE, UL, ErP, IEC 61800).
  • Managing the integrated motor-drive lifecycle: when your motor evolves, the drive must evolve with it.

WHAT KELD BRINGS TO MOTOR MANUFACTURERS

  • Custom drive design that is co-engineered with your motor R&D team for optimal system performance.
  • Control firmware developed for your motor type — sensorless, sensored, FOC, V/f, or hybrid algorithms.
  • A single partner for drive design, certification, and serial production — eliminating coordination risk between separate design houses and contract manufacturers.
  • Flexible production model that supports your motor product portfolio: multiple drive variants, varying batch sizes, and rapid changeovers.
  • Long-term partnership value: as we learn your motor families, we accelerate every subsequent project.
