Details
1、 Working principle of RS 775 brushed motor
1.1 Basic Structure
The basic structure of RS 775 brushed motor includes stator, rotor, brush, and commutator. The stator is equipped with fixed main magnetic poles, while the rotor is equipped with armature windings and commutators. When the electrical energy of the DC power supply enters the armature winding through the brush and commutator, armature current is generated. The magnetic field generated by the armature current interacts with the main magnetic field, thereby generating electromagnetic torque and driving the motor to rotate.
1.2 Working principle
The working principle of brushed DC motors is based on the interaction of magnetic fields. The static magnetic field of the stator surrounds the armature (rotor), and an external power source excites the armature magnetic field. When the motor rotates, the carbon brush slides on the commutator, generating a rotating magnetic field that attracts the stationary magnetic field of the stator. This magnetic field interaction causes the motor to continuously rotate, thereby driving the load.
2、 Principles for selecting RS 775 motors
2.1 Performance Parameters
When selecting an RS 775 motor, its performance parameters should be considered, including rated voltage, rated power, speed, torque, etc. The rated voltage is usually 12V, suitable for various DC power sources and battery packs. The rated power determines the output capacity of the motor, while the speed and torque directly affect the performance of the motor.
2.2 Speed regulation performance
The speed regulation performance of RS 775 motor is one of the key factors in selection. Common speed regulation methods include PWM speed regulation and voltage regulation. PWM speed regulation adjusts the voltage and current of the motor by changing the duty cycle, which has the advantages of wide speed regulation range, high accuracy, and high efficiency. Voltage regulation achieves speed control by changing the input voltage of the motor, with a simple structure but slightly lower speed control accuracy.
2.3 Application Environment
The selection of motors also needs to consider the application environment, including working environment temperature, humidity, vibration, etc. The RS 775 motor features high efficiency, low noise, and long lifespan, making it suitable for a variety of complex environments.
