What is a modified motor?
These can be split into two types; sport and handwound modifieds. Sport types are factory wound and cost from approximately 35.00. Handwound motors have the armature wound by hand and are hand assembled to achieve a higher level of performance with a retail price of approximately 60.00. All modifieds are ballraced and can be taken apart for cleaning. The commutator can be skimmed several times during it’s life to maintain the performance. A wide range of variations are available with different numbers of winds and turns. ‘Turns’ range from 7 to 30 – this is the number of times the wire is would on the armature. ”Winds’ is the number of pieces of wire on the armature and range from 1 (single), 2 (double) to 5 (quint) etc. In general the lower the number of turns the more speed & power the motor will have but it will of course use more battery power. The number of winds will determine how the power will be delivered; a single will give more punch whilst a quad will be smoother. The moto
The components of an electric motor are: – • The ‘can’ which holds the magnets in place • The ‘end-bell’ which houses the bearings, the brushes, and the electrical connections • The armature, which is divided into three segments around which the wire is wrapped Electrical current passes from the end-bell connections to the brushes and through the wires wrapped around the armature. The interaction between the current and the magnets makes the motor turn. The speed at which the motor turns, and/or the force exerted as it turns, varies according to the strength of the magnet(s) and the arrangement of the wires – as well as the amount of current flowing through the wires. Almost any combination is possible – limited only by physical size and desired performance. A modified motor is defined as follows: – • The wire is wound (turned) around each armature at least 6 times (compared to 27 times for the standard motor) • The wires can be wound in combination ‘sets’ – just one wire (single); two
