Title: Improvements in and relating to regenerative braking with valve-controlled alternating current motors
IPC: B60L7/16
Filed: 1933-06-10
Abstract: 421,061. Motors. AKT.-GES. BROWN, BOVERI, & CIE, Baden, Switzerland. June 10, 1933, No. 16683. Convention date, June 22, 1932. (Class 35] Machines with vapour or like rectifiers in place of commutators.-In a motor employing a valve system in place of a commutator, the excitation current is regulated during regenerative braking by the arrangement which regulates the voltage applied to motor during normal operation. As shown, the star points of two stator winding systems 3<a>, 3b are connected to a transformer 1 and the ends of the phases are connected to anodes 7 of a mercury vapour rectifier 6. With the switch 12 in the position I, the voltage applied to the motor is regulated by adjusting the grid voltage by means of a synchronously driven switch 13 which applies a selected portion of the control voltage wave to the grids through the distributers 5. To vary the moment of ignition of the valve anodes the segments of the switch 13 are turned either by the hand or by displacing the magnetic axis of rotor of the synchronous motor 14 driving the switch. This may be done by connecting the rotor windings 14b to a resistance 15 having sliding contacts. A phase displacer which displaces the control voltage with respect to the incoming voltage may replace the synchronously driven switch. The field winding 4 is supplied directly through auxiliary anodes 9 or through a separate rectifier from a transformer 10, but for regenerative operation the switch 12 is moved to position II whereby the rotary switch 13 is included in the field circuit. The distributers 5 are fed directly from the transformer 11 so that the ignition moments of the main anodes are fixed and the grid control voltage is displaced by approximately 180‹. During the change from one state of working to the other, the main and auxiliary anodes are blocked by means of a relay 17 energized from the sliding contacts of the resistance 15 which disconnects the centre point of the transformer 11 from the cathode 8 and connects it through a resistance 18 to the negative terminal of the battery 16. The switch 12 may be operated by hand or by means of a relay. Specifications 400,688 and 410,740 are referred to.
