層の数置の余地がある。A system combining a chopper device and a DC motor that has these features is also desired because of its high reliability. In other words, the conventional chopper device has great effects in terms of low maintenance due to no contact, elimination of resistance loss, and conservation of vehicle power due to regenerative braking. .

回路が複雑となること等の欠点がある。Conventionally, chopper control of an electric vehicle has been carried out using a chopper device that controls the field by I+1 and a belly band direct current flij+ machine, and a chopper family j? 7 and a direct current series winding '1α winding' are common. The former is a compound winding electric 'dl
For JI, in the C line and the regeneration ° C1 self-winding W (a and the shunt field are connected in a phase differential manner, and the characteristics are different, and the direction of 111.'tAf flowing in the shunt field A6 is -> i=
Therefore, switching between forward and reverse requires a reversing device that switches the armature circuit. The latter has drawbacks such as requiring a conversion device to switch between forward and brake, and between 00 and reverse, and that the field circuit becomes complicated in order to perform field control continuously.

事前に防ぐことができる。The figures will be explained below. In Fig. 2, (7) is a driving command converter that converts instructions from the driver's cab into digital signals, including power running - forward, power running - reverse, brake - forward,
A driving command discriminator that commands either brake or reverse,
01) is the polarity detector, and the field winding (E) detected by the current detector OQ? ! It is made up of a logic circuit that determines whether the polarity (direction) of the field current of υ matches the polarity of the field current according to the operation mode commanded by the operation command converter (7). (2) is an operation control circuit that controls the start and stop of the operation of the armature chopper device 0υ0da. In other words, the command from the driver's cab is judged by the driving command discriminator (7), and the polarity detector 6υ judges whether the current detected by the current detector OFj is flowing in the required direction according to the command. , and if that is correct, the armature chopper device 0υO
A signal is sent to the operation control circuit to permit the start of Z operation. If the current direction is reversed, the armature chopper device θ]
) Stop the operation of eta and leave it as is. By carrying out the above control, switching operations between power running and braking and between forward and backward movement can be performed reliably, and operations that may cause damage to the main circuit equipment can be prevented in advance.
