It typically includes a series of resistors. These resistors are used to vary the voltage and current delivered to the motor, thereby controlling its speed. A mechanical wiper arm moves across the resistor network to select different resistances. A standard RC servo motor is used to move the wiper arm. This servo is controlled by the receiver unit (via channel 2).<\/p>\n<p><a href=\"http:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5642\" src=\"http:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-scaled.jpg\" alt=\"\" width=\"1920\" height=\"2560\" srcset=\"https:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-scaled.jpg 1920w, https:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-225x300.jpg 225w, https:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-768x1024.jpg 768w, https:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-1152x1536.jpg 1152w, https:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-1536x2048.jpg 1536w, https:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-1246x1661.jpg 1246w, https:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-675x900.jpg 675w, https:\/\/rcpress.com\/wp\/wp-content\/uploads\/2024\/07\/IMG20240712162816-480x640.jpg 480w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A traditional mechanical speed controller (MSC) regulates the motor&#8217;s speed and thus control the car&#8217;s acceleration and deceleration.
