Study Notes
Electric Motors in Robotics
- Electric motors are electromechanical driven machines that convert electrical energy into mechanical energy, enabling motion in robots.
- They are widely used in robotics due to their compact and lightweight design, high power conversion ratio, excellent accuracy, and repeatability.
Importance of Electric Motors in Robotics
- Electric motors inject life into robots, enabling them to move and perform tasks.
- They are essential for robots to interpret their surroundings, move around, and actuate parts of their body.
How Electric Motors Work
- Electric motors work by harnessing the force of electromagnetism, produced by the interaction of electrically charged particles inside the motor.
- The different parts of the electric motor, including the armature, commutator, brushes, axle, stator, electrical terminals, and DC power supply, work in unison to enable the motor to function efficiently.
Key Concepts in Electric Motors
- Speed refers to the maximum speed a motor can reach, measured in revolutions per minute (RPM).
- Torque measures the force that a motor can produce or exert, and it has an inverse relationship with speed.
- Gears can be used to convert speed to torque or torque to speed.
Selecting the Correct Electric Motor
- When selecting a motor, consider the load that a specific motor can handle, the required torque, and the rotations per minute of the motor when it is running.
Parts of an Electric Motor
- The basic parts of an electric motor include an armature or rotor, a commutator, brushes, an axle, a stator, electrical terminals, and a DC power supply.
- These parts work together to utilize the attractive and repulsive forces of electromagnetism, causing the motor to continuously spin.
