Performance Characteristics of Non-Arc Double Stator Permanent Magnet Generator

Abstract

Abstract-The improvement in the power density in the double stator configurations is feasible with increase in the electrical loading of the electrical machines. This type of newer configuration is finding significant applications in improvising energy generation, more commonly for renewable energy generation. Various double stator configurations with non-arc permanent magnet machines for power density are modelled and analyzed in this paper. Finite Element Method (FEM) is used to simulate for the generation capability including the electromagnetics parameters such as flux linkage and open circuit voltage. A new slotted rotor structure is evolved based on the magnetic flux flow control inside the machine. The proposed structure is then fabricated in the laboratory and tested for operating characteristics with load circuit. The proposed machine produces a maximum power of 600 W at speed of 2000 rpm with 75% of maximum efficiency with the micro-hydro generation unit.

“…This shows that the best operating current of the motor is at 6 A. The relationship between torque with current is shown in equation (11) where P is number of pole, Z is number of conductor, ϕ is flux per pole, I is armature current and A is number of parallel path.…”

“…Double stator motor is widely used in electric vehicle because of its high power and high efficiency [4][5][6][7][8][9][10][11]. Some author uses double stator for hybrid electric vehicle (HEV) [12].…”

Modelling of torque and speed characterisation of double stator slotted rotor brushless DC motor

“…Here, ϕ M is the maximum flux in Wb, N the total number of turns in the inner and outer stator, and A mg the area of the magnet in m 2 . Flux linkage for the single magnetic circuit can be denoted by (19).…”

“…The slotted rotor can also hold the PM that makes the rotor more stable. The DSSR-BLDC has the higher torque to volume ratio compared with other BLDC motors and hence exhibits advantages such as high precision, fast response, large acceleration, small torque ripple, high overload capacity, high mechanical integration level, and flexible control system [16][17][18][19][20]. the PM to be held by a slot that makes the rotor more stable.…”
