33, 35, 42 & 48 Series AC Motors

Flexible AC motor platforms for OEM and industrial applications

The 33, 35, 42 and 48 series provide established starting points for compact industrial, commercial and OEM equipment. SDT reviews the electrical supply, required output, duty, mounting and operating environment to identify a suitable platform and configure it around your application.

Available motor configurations

Fixed- and Variable-Speed AC Solutions

Select the electrical configuration around the supply, starting requirement, speed control, duty and thermal conditions—not frame size alone.

PSC Single-Phase Motors

Capacitor-run configurations for quiet, low-maintenance fixed-speed operation in fans, pumps and compact commercial equipment.

Three-Phase Induction Motors

Compact fixed-speed configurations for continuous industrial duty, machinery and OEM equipment.

Inverter-Duty Three-Phase Motors

Variable-speed configurations for operation with a suitably matched VFD, with winding, insulation, cooling and operating range confirmed for the application.

Available as complete AC gearmotor solutionsExplore right-angle, inline, parallel-shaft and application-specific geared configurations.Explore More

Application-specific options

Define the AC Motor Around the Equipment

These four decisions connect electrical performance, installation and duty. Hover, focus or tap each item for the engineering implication.

Electrical

Confirm the supply voltage, phase and frequency alongside required output, speed, starting method and any need for variable-speed control.

What this provides

Mechanical

Define the shaft, mounting and overall envelope around the equipment, including flange or foot arrangement and gearbox interfaces where needed.

What this provides

Environment

Match the enclosure, ingress protection, finish and ventilation to the operating ambient, contamination and available cooling.

What this provides

Application

Review load behaviour, starting torque, duty cycle and thermal limits against the expected operating life and service conditions.

What this provides

Selection guidance

Choose the Right AC Motor Route

Start with an established motor where it meets the duty. If the supply, starting behaviour or mounting needs differ, explore a controlled modification or a new design.
