  • Single shaft: Provides a visible mechanical output shaft.
  • Solid yoke extension: Provides the specified structural extension.
  • Four-terminal arrangement: Facilitates instructional study of the motor's electrical connections.
  • Metal base: Provides stable support for laboratory use.

3. Experiments and Learning Objectives

The AL-E280 can be used for the following educational activities:

  1. Study of single-phase capacitor-start induction motor construction.
  2. Identification of stator, rotor, main winding, and auxiliary winding.
  3. Study of the function of the starting capacitor.
  4. Understanding the starting torque mechanism in single-phase induction motors.
  5. Study of the starting winding and main winding connections.
  6. Observation of the squirrel cage rotor and shaft arrangement.
  7. Understanding the operating principle of single-phase induction motors.
  8. Study of motor terminal identification and connection procedures.

4. Working Principle

A single-phase AC supply produces a pulsating magnetic field, which by itself does not provide sufficient starting torque in a conventional single-phase induction motor. The capacitor-start arrangement introduces a phase difference between the currents in the main and auxiliary windings, producing an approximate rotating magnetic field during starting.

This generates starting torque and initiates rotor rotation. In a conventional capacitor-start motor, a centrifugal switch or another starting mechanism disconnects the auxiliary winding and starting capacitor after the motor accelerates.

5. General Requirements

  • Suitable for electrical machines laboratories, polytechnics, engineering colleges, and technical training institutes.
  • Robust construction suitable for repeated laboratory demonstrations.
  • Internal components clearly visible through the cutaway sections.
  • Main and auxiliary windings identifiable for instructional purposes.
  • Secure mounting on a rigid metal base.
  • Clearly identified electrical terminals.
  • Safe operation using the specified supply voltage and appropriate electrical protection.

Specification verification note: The designations SPDP, 1P23, and 1C01 have been retained or interpreted as supplied; confirm the exact enclosure, protection, and cooling classifications with the manufacturer before tender submission. Also verify the four-terminal arrangement and starting-capacitor configuration against the actual motor design.
