Special Features

  • This instrument is a permanent magnet that generates a magnetic field to rotate the armature or generator. It is composed of stator, rotor, brush, bottom plate and manual mechanism.
  • When the armature coil rotates in a permanent magnetic field, the direction of the coil's cutting line changes periodically, and the direction and magnitude of the induced electromotive force also change periodically, that is, alternating current is generated.
  • AC power is supplied to the outside through the collector ring and brushes of the commutator. If the brushes are moved to the middle of the slip ring, where the copper half-ring is rectified, the output is DC.
  • To demonstrate the alternator, first move the brushes to the entire ring part of the current collecting ring, and then use a sliding rheostat and a DC current meter to form an external circuit.
  • Connect the output end of the generator to slowly rotate the rotor of the generator, the ammeter will clearly show the direction of current change, or you can use a DC voltmeter to connect to the output end for demonstration

Description

PurposeThis machine is used to demonstrate the basic structure and working principle of AC and DC generators for junior high school physics and elementary school natural knowledge teaching.Second, the structureThis instrument is a permanent magnet that generates a magnetic field to rotate the armature or generator. It is composed of stator, rotor, brush, bottom plate and manual mechanism.1. Stator: It is composed of a permanent magnet and a pole whip. The magnet is made of two pieces of barium constant magnetic material. The red is "N" pole, and the blue is "S" pole.2. Rotor: The armature is composed of a rotating shaft, a coil frame, an enameled wire, and a small pulley.3. Electric brush: It is made of elastic phosphor copper sheet, and by moving the position of the electric brush on the slide bar, alternating current and direct current can be obtained respectively.Board and so on.4. Bottom plate: It is made of double-engine board imported from West Germany. The board is equipped with the complete machine. 5. The manual mechanism, manual wheel and wheel frame are installed on the bottom plate and connected to the small pulley of the motor through a belt.Technical requirementsWhen the rotor speed is 1200-1600/min, the output voltage of the machine and the cutoff voltage are not less than 8V, and the load voltage is not less than 5V, 0.3A
