![]() ![]() ![]() Higher torque applied to the wheel = better ability to overcome obstacles / friction, climb up a slope etc.The equivalent of force for rotation is called Torque.Here is a good interactive tutorial on DC motors - Torque and Speed Control, if necessary, has to be achieved through some external control mechanism DC motors are used in applications which require good energy efficiency, but only imprecise control. ![]() The direction in which the coil of wire moves can be found using Fleming’s left hand rule.A DC motor uses a permanent magnet to exert a force on a current-carrying coil of wire.Hence, a magnetic field exerts a force on a moving electric charge.If an electric charge moves, it generates its own magnetic field, which interacts with the original field (from permanent magnets). ![]()
