Detailed analysis of discount 6v Gear Motor
There are two types of commonly used geared motors, called AC geared motors that operate on AC power, and DC geared motors that operate on DC power supplies.
The working principle of the discount 6v Gear Motor is to convert the input voltage signal into angular displacement or angular velocity output on the shaft. That is to say, the geared motor is a control motor whose speed and steering change with the magnitude and direction of the input voltage signal. The geared motor can carry a certain amount of load and act as an actuator in the automatic control system, so it is also called an actuator motor.
The performance requirements of the automatic control system for the geared motor can be summarized as follows.
(1) There is no rotation phenomenon. Before the control signal arrives, the rotor of the geared motor is stationary; after the control signal arrives, the rotor rotates rapidly; when the control signal disappears, the rotor of the geared motor should stop rotating immediately. When the control signal is zero, the phenomenon that the motor continues to rotate is called the "rotation" phenomenon. Eliminating the rotation is a necessary condition for the normal operation of the automatic control system.
(2) The no-load starting voltage is low. When the motor is unloaded, the rotor is started from a standstill to continuous operation regardless of the position. The small control voltage is called the starting voltage. The smaller the starting voltage, the higher the sensitivity of the motor.
(3) The linearity of the mechanical characteristics and the adjustment characteristics is good, and the speed can be smoothly and stably adjusted over a wide range.
(4) Good responsiveness. That is, the electromechanical time constant is small, and thus the geared motor requires a small moment of inertia.
