(a) Conventional electric drive was introduced in 1891 by Hary Ward Leonard (1861- 1915), an electrical engineer based in Cincinnati to drive passenger lift of large mines in the US. It has been the major drive for DC motor application throughout the century. However, modem electric drive has replaced the usage of the Ward-Leonard system in many industrial applications nowadays. Compare the pros and cons of Ward-Leonard system to modem electric drive. What would be your drive of choice? (11) If the operator wants to use a Ward-Leonard system to control the operation of a gantry system, can the motor use regenerative braking to reduce the speed when it approaches the target? Justify your answer.

A separately excited DC motor is supplied by a voltage U=230 V. In normal operation, the armature absorbs a current of I = 40 A. The resistance of the armature is R₂= 0.39 and of the field coil is R,= 120 92. The field coil supplied by a voltage U=140V. a A no-load test at the nominal speed gives the following results: U₁ = 225 V; I₁ = 1.2A. Calculate: a) The constant losses knowing that the Joule's losses in the armature at no load are negligible. b) The power absorbed by the armature. c) The Joule's losses in the armature and in the field coil. d) The efficiency of the motor (n). e) We want to limit the starting current in the armature to 80 A. What should be the resistance of the starting rheostat?

(a) A 100hp, 250V, 1200 rpm separately excited DC motor with amature resistance of 0.032 and a field resistance of 41.572 initially nuns with VA-250V, Ia=120V and rotates at 1103 rpm while supplying a constant torque load. If the motor is required to slow down to 879 rpm with the same load, what would be the firing angle at the 3-phase 240VAC RMS firing circuit connected to the amature circuit of the DC motor?
