Remote Control Car Motors By Michael Paetzold, Fri Dec 9th All types of racing cars have different types of motors. Somehave single or some have double. It is really confusing to tryto sort out the difference between a single our double motorcar. Plus a newbie into the world of remote control cars getseasily disoriented with what is a 13 turn double or a 13 turnsingle…? Well, in plain speaking language it refers to number of timesthe wires are wrapped around the armature. A 13 turn doublewould be 2 strands wrapped 13 times. A 13 turn single would be 1wire wrapped 13 times. The double wires have more torque whereas single wires have more speed. In general, it means that moreturns means more torque but less speed and vice versa. That’slower turns means lower torque and greater RPM. The number ofwinds describes how abruptly the motor accelerates. Fewer windswould mean less abrupt acceleration and more winds would lead tosmoother accelerations. Torque basically refers to how much a force is acting on motorthat causes motor to rotate. If there is more than one forceacting on a motor then each of these forces shall apply torque.The net torque acting upon the motor shall be the sum total ofall the forces or torques acting upon a motor. It is usuallyrequired for cars racing on the twisted tracks. Remote control cars come with two kinds of motors: the ones withbrush and ones without i.e. Brushless. The brushless motor haswindings located around the outside of the motor and the magnetsare located on the moving motor shaft. A brushless motor doesnot provide any friction The slot less and brushless motors are third generation motors.With slot less design, motor can achieve higher efficiency,torque, fast response time and longer life time with greaterwith zero maintenance. Cogging problem is also eliminated evenat lower speed operation. But since there is a lot of researchand development involved in their development they come out asexpensive solution in case of RC cars. There are also sensor less and motors with sensors. Sensormotors are older technology with less cogging, less rpm and lesspower. On the other hand sensor less motors are newer technologywith more power and more rpm. Both have difference of cogging onstart up. This can prove to be a little troublesome when you arein a race. It seems like forever for a sensor motor to start up.But sensor less motor gives smoother throttle response,efficient running and a fewer wires to mess up with. Remote control cars have a lot to do with the motors and theirfunctioning. When preparing for a race, checking out on motorscan be really helpful. If your car is heavy then may be a motorwith more torque would be required. A speedy light action racerwould need a greater rpm. Connections and wires to all themotors need to be properly fixed and checked. If you have somecash to spare for the race then going in for the slot less motorcan be good idea.
