Description
Technical field
The present invention relates to a kind of teaching mode, specifically a kind of being used for demonstrates the motor demonstrating model of motor principle.
Technical background
Motor is equipment electric energy being converted to mechanical energy, is the action principle utilizing electrical conductor stressed in magnetic field, and hot-wire coil two end lines have rightabout electric current simultaneously, makes the generation of whole coil around the torsion of axle, coil is rotated.
Direct current motor, due to the ubiquity of its usable range, also becomes physics teaching in secondary school aspect key content.But the at present demonstrating model of motor on the market, magnetic direction and intensity are all fixing, can only be used for the electronic situation of magnetic field demonstration intensity when fixing, and can not be used for the impact of magnetic field demonstration Strength Changes on Ampère force suffered by electrical conductor.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, provides a kind of motor demonstrating model, this model not only can demonstrating current on the stressed impact of electrical conductor, can also magnetic field demonstration intensity on the stressed impact of electrical conductor.
For solving the problems of the technologies described above, the invention provides a kind of motor demonstrating model, comprise base, rotor, rotor field spider, magnet and magnet support, described base is fixed with four guide bar receivers and two handle sets, four guide bar receivers are that quadrilateral is arranged, two handle sets are arranged symmetrically with, guide bar receiver is fixed with two guide rods, two guide rods are parallel to each other, two guide rod shared two magnet supports, two magnet supports are arranged symmetrically with, two magnet supports can slide along guide rod, respectively on two magnet supports fix a magnet, two magnet poles are relative, each hinged rigid link in the back of two magnet, rigid link and handle hinged, handle is hinged on handle set,
Rotor is between two magnet, and rotor internal fixtion has axle, and axle is hinged on rotor field spider, and axle is also fixed with flabellum, and flabellum is positioned at outside rotor field spider, and rotor field spider is fixed on base.
Described rotor is commercially available prod, and rotor includes hot-wire coil, and hot-wire coil two ends connect two brushes, and brush connects external power.
Principle of work of the present invention is: by upwards lifting handle, handle promotes two magnet along guide rod slide in opposition, two magnet spacings reduce, produce the magnetic field of some strength, be energized in rotor (hot-wire coil), according to Ampere theorem, hot-wire coil produces Ampère force in magnetic field, band moving axis rotates together, can observe this phenomenon by the rotation of flabellum.
Moving magnet is to another distance, same current is passed in coil, the change that the rotational speed of observing flabellum occurs, according to formula F=BILsin θ, (wherein F is Ampère force, the angle that B is magnetic field intensity, I is size of current, L is loop length, θ is magnetic field and coil), checking Ampère force size and magnetic field intensity proportional.
Motor demonstrating model structure of the present invention is simple, not only can demonstrating current on the stressed impact of electrical conductor, can also magnetic field demonstration intensity on the impact of the stressed size of electrical conductor, have more intuitive and operability.
