All About Remote Control (Radio-Controlled) Car Motors (Part 1)

All types of racing cars have different types of motors. Some have single or some have double. It is really confusing to try to sort out the difference between a single our double motor car. Plus a newbie into the world of remote control cars gets easily disoriented with what is a 13 turn double or a 13 turn single…?

Well, in plain speaking language it refers to number of times the wires are wrapped around the armature. A 13 turn double would be 2 strands wrapped 13 times. A 13 turn single would be 1 wire wrapped 13 times. The double wires have more torque where as single wires have more speed. In general, it means that more turns means more torque but less speed and vice versa. That’s lower turns means lower torque and greater RPM. The number of winds describes how abruptly the motor accelerates. Fewer winds would mean less abrupt acceleration and more winds would lead to smoother accelerations.

Torque basically refers to how much a force is acting on motor that causes motor to rotate. If there is more than one force acting on a motor then each of these forces shall apply torque. The net torque acting upon the motor shall be the sum total of all the forces or torques acting upon a motor. It is usually required for cars racing on the twisted tracks.
