SDT’s high-efficiency motor, drive and geared-motor solutions are developed to reduce energy use while supporting reliable performance and productive operation across demanding industrial applications. Each route is selected around the required duty and installation conditions, providing a practical path to an efficient, straightforward-to-integrate solution.
Choose the supply and drive architecture first. Exact voltage, current, torque, speed and power are then released for the selected configuration.
LINE-OPERATED AC
IE1–IE4 AC Motor Solutions
Established IEC induction-motor platforms for fixed-speed and inverter-controlled industrial duties. Efficiency class, frame, mounting and protection are selected against the application and destination market.
Direct-on-line or VFD operation where the selected motor permits
IEC mounting, enclosure and mechanical options
Model-specific efficiency and performance evidence
High-efficiency synchronous and permanent-magnet routes developed around a compatible drive, operating envelope and control strategy—not as an isolated motor claim.
Motor, drive and control method evaluated together
Continuous and peak duty confirmed by application
Efficiency class, rating and evidence confirmed for the selected model

OUTPUT-LED SELECTION
High-Efficiency Geared Drive Systems
Efficient motors combined with the gearbox architecture and ratio required at the driven shaft. Selection begins with output torque, speed, duty and service conditions.
Inline, parallel-shaft, right-angle and planetary routes
Motor technology and ratio matched to the load
Output performance and service factor released by configuration
Representative motor-and-drive routes shown as one coordinated selection framework. Final technology, ratings and control configuration are confirmed for the application.
SYSTEM-LEVEL ENGINEERING
Products Designed to Work Together
SDT selects the motor, drive, gearbox and control method as one coordinated system—based on the supply architecture, load profile, duty cycle, installation envelope and required driven output.
Matched motor and drive operating envelope
Gear ratio and service factor selected from the driven duty
Configuration-specific ratings and compliance evidence
Why it matters +
CUSTOMER VALUE
One Coordinated Basis for Selection
Selecting the motor, drive, gearbox and control method together reduces integration risk, avoids mismatched ratings and gives the OEM one clear performance basis for validation and release.
Looking for EC or compact brushless technology?These specialist products remain available in their dedicated technical ranges rather than being mixed into the main IE motor comparison.
TECHNICAL SELECTION
Information Released Against the Application
Published platform information supports route selection. Project-specific ratings and evidence are confirmed only after the operating conditions and final configuration are defined.

EFFICIENCY FRAMEWORK
Use the Right Claim for the Right Architecture
LINE-OPERATED MOTOR
IEC 60034-30-1
IE classification applies to eligible motors operating from a sinusoidal supply within the standard’s scope.
CONVERTER-FED MOTOR
IEC TS 60034-30-2
Variable-speed motors require the converter-fed test and classification framework applicable to the selected design.
MOTOR + DRIVE SYSTEM
IEC 61800-9-2
Power-drive-system assessment considers motor and drive losses at defined operating points.
Terminology matters: a gearbox is not classified as IE5. A geared solution may use an IE5-class motor, while gearbox and complete-system losses are stated separately.
