The present invention relates to DC shunt (or) compound motor with controllable dynamic characteristics, and particularly to a shunt field having one set of basic exciting field current and field current being increased following the increase in armature load current to produce similar characteristics to series motor, and field exciting current is stopped increasing when maximum setting value is up so as to produce similar characteristics to shunt motor; except comprising a single motor, the present invention may further include interlock motors to achieve the function of synchronous or proportional operation, and it is characterized that, it may direct-proportion control the field current value of neighboring motor (forward or backward) in sequence by means of detecting the value of armature load current of first motor, and direct-proportion control the field of first motor by means of detecting the value of armature current of ultimate motor to enable motor set appearing synchronous or synchronous-alike or proportional operation. |
