DC motors were the first type widely used, since they could be powered from existing
direct-current lighting power distribution systems. A DC motor's speed can be controlled
over a wide range, using either a variable supply voltage or by changing the strength of
current in its field windings. Small DC motors are used in tools, toys, and appliances. The
universal motor can operate on direct current but is a lightweight motor used for portable
power tools and appliances.
2. What
’
s L9110 ?
L9110 is a driver chip which is used to control and drive motor. The chip has two TTL/CMOS
compatible input terminals, and possesses the property of anti-interference: it has high
current driving capability, two output terminals that can directly drive DC motor, each output
port can provide 750~800mA dynamic current, and its peak current can reach 1.5~2.0A;
L9110 is widely applied to various motor drives, such as toy cars, stepper motor, power
switches and other electric circuits.
OA, OB: These are used to connect the DC motor.
VCC: Power supply (+5V)
