An inverter-controlled ac induction motor propulsion system for rail transit cars was designed, developed, and tested to verify projected benefits and applicability of ac over conventional dc cars. Two New York City Transit Authority (NYCTA) R-44 dc subway cars were retrofitted with prototype ac propulsion equipment based on mature, low-risk ac propulsion technology. The program showed that propulsion systems using ac motors can provide greatly improved reliability and reduced maintenance, with significant reductions in life-cycle costs. Demonstrated on the NYCTA, the ac propulsion system improved acceleration and braking performance with good electromagnetic interference and acoustic noise control and was fully compatible with the existing trainlines, NYCTA signalling and supervisory equipment, and dc cars. The report explains how the latest technology would be applied in future production equipment to result in even more benefits to the rail transit industry.
