1. Technical Specifications

2. Constructional Features

• Stator assembly: Laminated steel core with windings to demonstrate the generation of the magnetic field.
• Rotor assembly: Rotating component used to demonstrate electromagnetic torque production.
• Cut-section construction: Selected portions of the motor housing are opened or removed to allow visual inspection of internal components.
• Single shaft: Provides the mechanical output arrangement.
• Solid yoke extension: Incorporates the specified structural extension.
• Terminal arrangement: Two specified terminals for the intended instructional connections, subject to the actual motor wiring.
• Metal mounting base: Provides stable support for laboratory demonstrations.

3. Experiments and Learning Objectives

The AL-E301 cut-section motor is suitable for the following educational activities:

1. Study of single-phase induction motor construction.
2. Identification of stator, rotor, shaft, and magnetic core.
3. Understanding the production of a magnetic field in a single-phase motor.
4. Study of the starting principle of single-phase induction motors.
5. Observation of internal motor components through the cutaway sections.
6. Understanding the relationship between rotor speed, synchronous speed, and slip.
7. Study of motor terminal identification and basic electrical connections.
8. Comparison of different single-phase motor starting methods.

4. Working Principle

A single-phase AC supply produces an alternating magnetic field in the stator. A conventional single-phase induction motor is not inherently self-starting, so an appropriate starting arrangement is required.

In a split-phase motor, an auxiliary starting winding is designed to create a phase difference relative to the main winding, producing starting torque. In a capacitor-start motor, a capacitor provides a greater phase shift to improve starting performance. In a shaded-pole motor, a short-circuited shading coil produces the phase shift needed for starting.

These are different motor designs. The supplied description mentions a capacitor, split-phase starting, and a “split pole” motor; therefore, the exact starting method should be verified against the actual AL-E301 motor before finalizing the technical description.

5. General Requirements

• Suitable for electrical machines laboratories, engineering colleges, polytechnics, and technical training institutes.
• Robust construction suitable for repeated educational demonstrations.
• Internal motor components clearly visible through the cut sections.
• Secure mounting on a rigid metal base.
• Clearly identified terminals for instructional use.
• Suitable for supervised laboratory demonstrations using appropriate electrical protection.

Technical verification note: The designations SPDP, 1P23, and 1C01 have been retained or interpreted from the supplied details. Confirm the exact enclosure, protection, and cooling classifications with the manufacturer. Also verify whether AL-E301 is a split-phase, capacitor-start, or shaded-pole motor, since these terms describe different construction and starting arrangements.
