A Comparative Study between Load and No-Load condition of Brushless DC Motor Drives by Using MATLAB

Upama Das, Pabitra Kumar Biswas, Sukanta Debnath

Abstract


In this paper an extensive comparative performance study is carried out between No-load and load condition of an open
loop model of a Brushless Direct Current (BLDC) Motor drive fed from a two-level voltage source inverter (VSI) under 120-
degree conduction mode, using simulations in a MATLAB based software environment. BLDC motors are currently growing
in popularity and replacing the brush motor in many applications, as they can be used in both low and high-speed vehicle
systems and also in servo drives. The high reliability, torque to inertia ratio, high efficiency, high power density, ease of
control and mainly the brushless operation make BLDC motors superior to others. It has a permanent magnet as a rotor with
a balanced 3-phase armature in its stator. The armature winding is driven by a power electronics inverter which is switched
in synchronism with the rotor position, sensed by an optical encoder or a Hall Effect sensor. It is found that torque ripple can
be minimized by tuning the value of rotor position, no load condition and trapezoidal armature phase current. The different
performance parameters for no-load and load condition of the BLDC motor such as phase voltages, phase currents, speed,
electromagnetic torque, d and q axis current and rotor position etc. are determined in MATLAB environment.
