Hand-Wound Motor and Generator Unit for U-Core Assemblies

Description

The Hand-Wound Motor and Generator Unit for U-Core Assemblies, also known as a classroom motor-generator apparatus or DC dynamo demonstration unit, is designed for practical demonstrations of motor and generator principles. The compact and strongly built unit can be hand-wound using a wheel and belt, allowing students to generate output voltage manually during generator demonstrations. The belt can be easily removed when the unit is operated as a DC motor, supporting comparison between motor action and generator action using the same apparatus.

The unit can run with a permanent U-shaped magnet or can be fitted into the U core as part of the Hodson Induction Kit as listed. When used with the U core, a compatible coil can be placed on the core to create the DC field. The field strength can then be altered to study how magnetic field strength affects motor or generator behaviour. The apparatus is constructed for reliability and long service life, with ball race bearings, a good quality commutator and robust sprung brushes as listed.

LEDs are included to monitor the output voltage and indicate the polarity of the output, making it easier to observe generator behaviour during classroom demonstrations. The motor is listed to run well with good torque at about 6 V DC, subject to compatible power supply and experimental setup. Users should confirm U core compatibility, magnet arrangement, coil specification, field supply, motor supply, belt setup and experiment procedure before use. Use only with compatible low-voltage DC power supplies. Do not connect the apparatus to mains voltage or unsuitable high-current sources.

Keep fingers, loose clothing, hair and cables clear of the rotating wheel, belt and shaft during operation. Magnets and powered coils can affect magnetic-sensitive devices. Keep electronic devices, magnetic storage media and medical devices away where required by institutional safety procedures. This product is intended for laboratory or educational settings only and should be used under appropriate supervision. This item is supplied as the selected hand-wound DC motor / generator only. U core, coil, permanent magnet, power supply, leads, meters, belt replacements, worksheets, PPE and additional induction kit accessories are not included unless specified separately.

LabChoice Australia supplies DC Motor / Generator apparatus and electromagnetism teaching equipment for school science laboratories, university teaching laboratories and educational facilities requiring practical demonstrations of motor action, generator output and magnetic field effects.
