Construction of Dc motor (all parts of dc motor in details)

Construction of Dc motor. Construction of Dc motor nearly looks like the construction of Dc generator, originally when the Dc machine starts working we can’t identify whether it’s a Dc generator or motor, briefly Dc motor consists of:. Stator: it’s the stationary part containing the field winding and receives the supply. Rotor: which is the rotating part.

Brushless DC (BLDC) Motor Construction and Working

This article explains about BLDC motors in details. Construction of a BLDC Motor. A commutator-brushes arrangement helps in achieving unidirectional torque in a typical dc motor. Obviously, commutator and brush arrangement is eliminated in a brushless dc motor. Here, an integrated inverter/switching circuit is used to achieve unidirectional torque.

Fan efficiencies differ from design to design and also by types. Typical ranges of fan efficiencies are given in Table 5.2. Fans fall into two general categories: centrifugal flow and axial flow. In centrifugal flow, airflow changes direction twice once when entering and second when leaving (forward curved, backward curved or inclined, radial) (see Figure 5.1). Table 5.2 Fan Efficiencies

4 Improving Fan System Performance Axial fans, as the name implies, move an airstream along the axis of the fan. The air is pressurized by the aerodynamic lift generated by the fan blades, much like a propeller and an airplane wing.

AN885, Brushless DC (BLDC) Motor Fundamentals

when describing BLDC motors. CONSTRUCTION AND OPERATING PRINCIPLE BLDC motors are a type of synchronous motor. This means the magnetic field generated by the stator and the magnetic field generated by the rotor rotate at the same frequency. BLDC motors do not experience the “slip” that is normally seen in induction motors. BLDC motors come in single-phase, 2-phase and 3-phase

Figure 4.28 shows a comparison between a double-outlet fan and a double-inlet single-outlet fan of similar construction. Three curves show the performance of the double-outlet fan at three different conditions. In these conditions, one channel is set to 0%, 50% and 100% of the maximum flow rate, and the other is open. The figure shows that a double exit fan can produce a higher volumetric flow

Three Phase Induction Motor: Construction and Working

Construction of Three Phase Induction Motor. Like any electric motor, a 3-phase induction motor has a stator and a rotor.The stator carries a 3-phase winding (called stator winding) while the rotor carries a short-circuited winding (called rotor winding).. Only the stator winding is fed from the 3-phase supply.
