AC and DC Motor Model /Physics Instrument AC/DC Generator Model

AC/DC generator model
Product Introduction
It can be used as motor and generator by changing connecting wire.
When the armature coil rotates in the permanent magnetic field, the direction of the cutting line of the coil changes periodically, and the direction and magnitude of the induced electromotive force also change periodically with the action, that is, the alternating current is generated, and the alternating current is supplied to the outside through the collector ring and the brush of the commutator. If the brush is moved to the middle of the slip ring, that is, the position rectified by the copper half ring, the output is direct current
The generator is a permanent magnet rotating armature type that generates magnetic field
Product Specification

1. Most of the faults of this instrument are loose and broken wires (due to moisture and corrosion). Therefore, such as:

1. The clearance between the armature and the pole shoe is very small. If the bearing is loose, the armature is easily stuck. At this time

Check the cause and adjust the position of the pole shoe and the bearing so that the armature can rotate flexibly in the pole shoe. peacetime
Pay attention to proper lubrication of bearings.
3. The belt shall be protected from oil contamination and high temperature. After use, the belt shall be removed from the pulley to
Prevent the belt from being too loose and slipping.
4. the brush terminal should be insulated from the support. If the screw is loose and short circuited, it should be adjusted.
