Variable Speed Drives
Precise motor control, custom-engineered for your application.
KELD designs and manufactures variable speed drives (VSDs) for BLDC, PMSM, and AC induction motors across a wide power range. Our drives are not general-purpose units adapted to your needs — they are purpose-built solutions, optimized for your motor, your load profile, and your operating environment.
TYPICAL APPLICATIONS
- Fans and air-handling units for HVAC and ventilation systems.
- Pump drives for water treatment, irrigation, and industrial processes.
- Compressor control for commercial and industrial refrigeration.
- Industrial actuators and automation components.
WHAT MAKES OUR CONTROLLERS DIFFERENT
- Application-specific firmware and control algorithms, not generic parameter sets.
- Hardware designed for your voltage, current, and environmental requirements.
- Optimized BOM: we include what your product needs, nothing more — delivering better cost-performance than general-purpose alternatives.
- Full compliance support: CE, UL, and other standards relevant to your target markets.
- Integrated IoT-ready connectivity where required.
PRODUCT FAMILIES
KMD Series: Next-generation motor drives for demanding HVAC, refrigeration, and industrial applications. Configurable across power ranges, motor types, and communication protocols.
Legacy and custom drive platforms: purpose-built solutions for specific OEM requirements, including high-power, multi-motor, and specialized control architectures.
INTEGRATION & INDUSTRIALIZATION
Every drive project follows our standard industrialization process: co-design review, DFM/DFT optimization, prototype validation, compliance testing, series-zero approval, and transition to serial production. Our flexible manufacturing model handles both low-volume launches and high-volume runs within the same quality framework.
