You can investigate three-phase integer-slot, fractional-slot and concentrated windings, both with single and double winding layers where appropriate. (Induction, DC & AC Motor consume around 1kw/hour) so it is 50% of power saving by magneto electric motor. Keep in mind that you will need to have the information that describes which motor winding corresponds to which encoder commutation signal before trying to align an optical encoder to a BLDC motor. of EEE, Mar Athanasius College Of Engineering, Kothamangala m, Kerala, India Associate Professor , Dept. The BLDC motor as the name suggests, does not use brushes for energising the motor phases; thereby eliminating all the mechanical wear and tear due to friction and power losses, and to arcing that are associated with its conventional brushed counterparts. Unlike conventional brushed type DC motor, wherein the brushes make the mechanical contact with commutator on the rotor so as to form an electric path between a DC electric source and rotor armature windings, BLDC motor employs electrical commutation with permanent magnet rotor and a stator with a sequence of coils. Inputs - Dimensions, material properties, and winding information : Outputs - Magnetic Circuit information, including flux densities and MMF drops, mechanical information, weights, inertias, winding information - including copper weights, resistance, slot fill, speed-torque, current, efficiency, losses, motor constants, and cost data of design. Inside the motor, an electronic commutator converts the applied DC voltage to a trapezoidal wave that is in sync with the rotation of the rotor, to power specific windings "servo" is a misnomer, derived from "servo-loop", which is something completely different. Below is a given table which compares both Star and delta connections showing the exact difference between Star (Y) and Delta (Δ) Connections. The +12V supplies the 3 phase bridge circuit which is the same as the motor supply voltage. What is common to all the members of this fam-ily is that the basic physical process involved in their operation is the conversion of electromagnetic energy to mechanical energy, and vice versa.
