Electromagnetic Demonstration Motor Structural Model Principle and Structure Model of Electric Motor, Electromagnetic Demonstration, Physics Teaching Instrument Electric

The main technical parameters of the instrument: Demonstrate DC Generator: stator plus 6V voltage, rotor speed is 180 rev/min, motor output is greater than 80uA Demonstrate the alternator, the stator is added with 6V voltage, and the output of the motor makes the current meter pointer deflect left and right; The insulation resistance between the conductor and the base is not less than 10KΩ; The electronic and rotor are excited, and the rated working voltage is 24V. The continuous working time is not less than 1 hour.

• The product consists of a base, a closed hoop, an electromagnet, a pole piece, an armature, a commutator, a rotating shaft, a brush, a rocker, a handle, and the like.
• The closed iron ring and the pole piece are made of iron plate with a thickness of about 3mm. The width of the iron ring is about 75mm and the outer diameter is about φ180mm. The iron ring and the pole piece are painted with red and blue paint.
• The electromagnet is wound on the iron core by QZ high-strength enameled wire. The two electromagnet coils are connected in series with each other. The armature is a rectangular multi-turn coil with a coil size of about 140×70mm. Both ends of the coil are made of red and blue tape. Bandaging.
• The commutator is a combined current and reversing device consisting of two combined copper rings with a size of φ22×30mm; the rotating shaft is made of φ8mm round steel and has a length of about 150mm; the brush is made of tin bronze of δ0.3mm. Film production, length 80mm, width 7mm.
• Demonstrate DC motor: stator and rotor series excitation, add 4V to 16V voltage, variable speed; stator and rotor are excited, add 10V to 6V voltage, variable speed.
