Electric toys are common toys in modern life. They can move and produce various interesting sounds and lights. The power of these movements comes from the motor. There are many types of motors for electric toys. The following will introduce several common motors and their applications in electric toys.
First of all, DC motors are one of the most commonly used motors in electric toys. The DC motor has a simple structure and consists of an armature, a permanent magnet and a reducer. The armature is a coil of copper wire that rotates in the magnetic field of a permanent magnet when energized. The speed of a DC motor can be controlled by changing the DC voltage of the armature, so it is very suitable for use in toys that require adjustable speed, such as remote-controlled cars, airplanes, and boats. In addition, DC motors are a lower-cost motor choice because of their simple structure and relatively low price.
Secondly, a stepper motor is another common type of motor that can rotate at a predetermined angle and number of steps. Stepper motors work by converting electrical pulse signals into discrete rotations of mechanical angles. It can control rotation with high precision and reliability, and does not require a reducer, so it is suitable for use in toys that require high precision, such as robots, puzzle machines, and 3D printers.
In addition to DC motors and stepper motors, there is also a type of motor called a brushless motor. Brushless motor, also called permanent magnet synchronous motor, is a new type of motor that can achieve efficient and energy-saving rotational power output. The controller of this kind of motor requires a high-precision, high-speed digital signal processing unit, so the cost is high. In toys, common applications are in toys that require high-speed rotation, such as aircraft, racing cars, and football robots.
In addition, there is a type of motor called a brushed DC motor. Its structure is similar to that of a DC motor, but it requires continuous maintenance of the brushes to maintain normal operation. This kind of motor is relatively rarely used in toys because it requires high maintenance costs and is prone to problems such as brush sparks and noise.
In short, electric toys can use many types of motors. Each motor has its own unique characteristics and advantages. The corresponding motor type can be selected according to different needs. With the continuous advancement of science and technology and the increasing maturity of motor technology, electric toys will become more intelligent, convenient and interesting.
