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.

Technical Discovery Call

You have an application or project in mind and want to explore whether KELD is the right partner. We will schedule a call with the relevant engineering team to discuss feasibility, approach, and next steps. No commitment, no sales pitch — just a technical conversation.
