Not sure which motor technology fits?
Share the environment, envelope, performance, power source and duty cycle. SDT will help define the appropriate product and development route.
Choose the right development route
From Standard Platforms to Complete Motion Systems
Once the closest product family is identified, SDT establishes whether the requirement is best met by a standard platform, a modified product or a new development.
Application-specific development
Bespoke Product Solutions
When published platforms cannot meet the duty, SDT can engineer a modified motor, a new development or a complete motion assembly around the application and production requirement.

Motor Efficiency and Matched Drive Selection
Compare AC, EC and brushless options using efficiency evidence appropriate to each motor. For a motor-and-drive package, assess the combined power-drive-system losses separately from the motor's IE class.
IE3–IE4 AC Motors
Industrial three-phase platforms selected around supply, frame, enclosure and operating duty; efficiency classification is confirmed for the selected model and test basis.
High-Efficiency EC Technologies
Outer-rotor, flat and integrated electronically commutated solutions for efficient variable-speed air movement and equipment integration, with any IE claim confirmed for the selected model and test basis.
Brushless Motor & Controller Integration
BLDC/PMSM platforms supplied motor-only for external electronic commutation, with a matched controller or as an integrated motor-and-controller package.
Legacy IE1 and IE2 motors: supported through replacement and upgrade review rather than promoted as the preferred basis for new energy-conscious equipment.
Complementary components
Matched Around the Selected Motor
Supporting components are specified as part of the motor or motion solution—not presented as separate primary product families.
Drives & Controllers
Matched speed controllers, inverters and servo drives selected with the motor.
Feedback Devices
Hall sensors, encoders and resolvers for speed, position and motion feedback.
Brakes
Holding, fail-safe and application-specific brake arrangements where required.
Mechanical Integration
Shafts, flanges, mountings, couplings and interfaces configured around the equipment.
