Abstract
The present invention relates to a teaching aid, particularly, a brushless direct current motor demonstration model. According to the brushless direct current motor demonstration model, an aluminum shell rotor is arranged on a support; a coil which is fixed on a base is arranged around the rotor so as to be adopted as a stator; one side of the aluminum shell rotor is provided with a sensor, a controller and a power generation coil, wherein the power generation coil is connected with a small light, and the sensor and the controller are connected with a power supply and a power supply switch. With the brushless direct current motor demonstration model of the invention adopted, students can have a further understanding of a relationship between electricity and magnetism, and the impression of the students on the electricity and the magnetism can be deepened.
Description
Technical field
The present invention relates to a kind of teaching aid.
Background technology
Teacher, in the time saying electromagnetic field and current relationship, need to have a demonstrating model to make demonstration, deepens thus the knowledge impression of classmate to electricity and magnetic.
Summary of the invention
The object of the invention is to provide a kind of brshless DC motor demonstrating model.Brshless DC motor demonstrating model is made up of aluminum hull rotor, stator, power coil, bulb, sensor, controller and 12V battery, power switch.The aluminum hull peritrochanteric of brshless DC motor demonstrating model arranges stator coil, is provided with power coil, sensor and the controller of lampet, and sensor is connected with power supply with controller.Turn on the power switch, can make the rotor of brshless DC motor demonstrating model, lampet is lighted simultaneously, thus, makes student have further understanding to electricity and the relation of magnetic, has deepened the impression with magnetic to electricity.
Brshless DC motor demonstrating model is that an aluminum hull rotor is placed on a support, is fixed on coil on base as stator in peritrochanteric setting, is also provided with sensor and controller, power coil in aluminum hull rotor one side, connects lampet on power coil; Sensor is connected with power supply, power switch with controller.
The beneficial effect that adopts brshless DC motor demonstrating model is to make student have further understanding to electricity and the relation of magnetic, has deepened the impression with magnetic to electricity.
Accompanying drawing explanation
Fig. 1 is the structural representation of brshless DC motor demonstrating model.
Embodiment
With reference to Fig. 1, brshless DC motor demonstrating model is that an aluminum hull rotor 1 is placed on a support, the coil being fixed on base is set around rotor 1 as stator 4, also be provided with Hall element as sensor 2 in rotor 1 one sides, sensor 2 and controller 3, power coil 6 and power supply, power switch connects, after switch opens, in the time that forwarding certain position to, rotor 1 sends signal to controller 3, and control circuit is switched on to stator coil 4, rotor 1 rotates under the interaction in electric current and magnetic field, now, be located at power coil 6 generation current under the effect of rotating magnetic field of rotor 1 opposite side, this electric current is lighted the lampet 5 connecting on power coil 6.
