DC Motor Types

Brushed DC Motor

Brushed DC motors work by having the coil rotate inside the surrounding magnets. The rotation of the coil causes the contact between commutator and brush to alternate, therefore switching the current flow through the coil. As a result, the brushed DC motor can operate.

Brushless DC Motor

A Brushless DC Motor (BLDC) is an electric motor powered by a direct current voltage supply and commutated electronically instead of by brushes like in conventional DC motors. BLDC motors are more popular than the conventional DC motors nowadays, but the development of these type of motors has only been possible since the 1960s when semiconductor electronics were developed.

Gearbox Types

Worm Gearbox

Worm gears operate by the friction created by turning lubricated gears. The friction is then converted into heat. By producing a low speed and high-speed torque level, worm gears are utilised as speed reducers, which implies that they are ideal for several applications. In theory, a worm gear is self-locking when the static friction angle is larger than the helix angle of the worm. The static friction angle is described as the angle where the load above will start to move.
