Hello, I am using the Cuk converter along with PMBLDC motor with following rating - Rated power: 0.816 kW; rated speed: 1500 r/min; rated torque: 5.2 N · m; poles: 6; stator resistance (R): 3.57 Ω/ph; inductance (L +M): 9.165 mH/ph; back EMF constant (Kb):1.3 V · s/rad; inertia (J): 0.068 kg · m2;
Coverter design values Vdc =298 volts ,Vs=220v and Is(source current) rated = 4.5 A The design values are obtained as Li = 6.61 mH, C1 = 0.3 μF,Lo = 0.82 mH, and Cd = 1590 μF. duty ratio =60%
the block i am using for BLDC motor is the PMSM from simpower block.
1. Do i need to put the additional load resistance also with this motor? if yes how to calculate that. In my model the dc link voltage is not boosting up to required 298 volts?. What may be the reasons.Suggest what may be wrong.. 2. How to calculate the voltage constant for this motor? Currently my value is 136.1. Is it correct?
