Abstract
Disclosed herein is a direct current motor control or energizing circuit comprising a direct current motor, a bank of series connected batteries, which bank includes opposite ends, and a switching arrangement for electrically disconnecting and connecting the bank to the motor for energizing of the motor at selective levels of potential and so that successive energizations involve alternate connection of the motor from the opposite ends of the bank to at least one of the batteries.
Claims28
A direct current motor energizing circuit comprising a direct current motor, a bank of series connected batteries, said bank including opposite ends, and switch means for electrically disconnecting and connecting said bank to said motor, said switch means including means operable so that successive energizations of said motor are alternately from said opposite ends of said battery bank.
A direct current motor energizing circuit comprising a direct current motor, a bank of series connected batteries including a postive end terminal and a negative end terminal, a speed control switch including a first plurality of contacts connected to said battery bank and including a first end contact, a second plurality of contacts connected to said battery bank and including a second end contact, a first switch contact, a second switch contact, and an actuator operative to selectively electrically connect and disconnect said first switch contact with said contacts of said first plurality of contacts and to selectively electrically connect and disconnect said second switch contact with said contacts of said second plurality of contacts, and switch means connected to said end contacts, to said motor, and to said end terminals of said battery bank and operative in response to operation of said actuator alternatively to electrically connect one or more of said batteries to said motor so as to drive said motor in a given direction and so as to drain said batteries from one of said end terminals of said battery bank and to electrically connect one or more of said batteries to said motor so as to drive said motor in said given direction and so as to drain said batteries from the other of said end terminals of said battery bank.
A direct current motor energizing circuit comprising a direct current motor, a bank of series connected batteries including a positive end terminal, a negative end terminal, and a plurality of intermediate terminals of respectively located between adjacent of said series connected batteries, a speed control switch including a first plurality of contacts including a first series of contacts and a first end contact, a second plurality of contacts including a second series of contacts and a second end contact, a first switch contact, a second switch contact, and an actuator operably movable to selectively electrically connect and disconnect said first switch contact with said contacts of said first plurality of contacts and to selectively electrically connect and disconnect said second switch contact with said contacts of said second plurality of contacts, first leads respectively electrically connecting said contacts of said first series thereof to said intermediate terminals in a first sequence beginning with said intermediate terminal adjacent one of said end terminals and continuing to said intermediate terminal adjacent the other of said end terminals, said first leads respectively including therein first diodes having respective annodes respectively connected to said intermediate terminals, second leads respectively electrically connecting said contacts of said second series thereof to said intermediate terminals in a second sequence opposite to said first sequence, said second leads respectively including therein second diodes having respective cathodes respectively connected to said intermediate terminals, switch means connected to said end contacts, to said motor, and to said end terminals of said battery bank and operative in response to operation of said actuator alternatively to electrically connect one or more of said batteries to said motor as as to drive said motor in a given direction and so as to drain said batteries from one of said end terminals of said battery bank and to electrically connect one or more of said batteries to said motor so as to drive said motor in said given direction and so as to drain said batteries from the other of said end terminals of said battery bank.
A direct current motor energizing circuit comprising a direct current motor, a bank of series connected batteries including a positive end terminal and a negative end terminal, a speed control switch including a plurality of contacts connected to said battery bank, a switch contact, and an actuator operative to selectively electrically connect and disconnect said switch contact with said contacts of said plurality of contacts, and means electrically connecting said motor to said battery bank and to said switch contact and electrically connecting said plurality of contacts to said battery bank including switch means operative in response to operation of said actuator alternatively to electrically connect one or more of said batteries to said motor so as to drive said motor in a given direction and so as to drain said batteries from one of said end terminals of said battery bank and to electrically connect one or more of said batteries to said motor so as to drive said motor in said given direction and so as to drain said batteries from the other of said end terminals of said battery bank.
