Abstract

Disclosed herein are a motor acceleration apparatus and a motor acceleration method. The motor acceleration apparatus includes: a rectifying unit converting household power into direct current (DC) voltage to output the converted DC voltage; a switching converter switching the DC voltage output from the rectifying unit in an alternating current manner so as to drive a two-phase switched reluctance motor (SRM) ; and a microprocessor controlling the switching converter at the time of initial acceleration of the two-phase SRM so that an initially set dwell angle is changed to a dwell angle in a normal operation state and starting advanced-angle control.

Description

[0001] Cross-references to related fields [0002] This application claims the benefit of Korean Patent Application No. 10-2013-0123528, filed Oct. 16, 2013, entitled "Motor Acceleration Apparatus and Method," the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a motor acceleration device and a motor acceleration method. Background technique [0004] Switched reluctance motors (SRMs) are one of the older motors that have been in use for over 150 years. Since power semiconductors have been developed, this traditional type of reluctance motor has become known as switched reluctance motor to meet the needs of variable drives. [0005] 'Switched Reluctance' is named by S.A. Nasar, which means two main features of SRM. [0006] Firstly, the expression "switching" means that the motor should always be operated in a continuous switching pattern. According to the research and development and progress of new power se...
