Abstract

Methods and tools For preventing too high speed Of electric cars With a DC motor winding parallel to the coil Armature Wire And the serial magnetic field windings are connected respectively with Close-open device And to the source of The DC power on the golf cart panel includes a modified control car. And connect to control Currents in each armature part and the magnetic field coil for The speed is controlled in a manner that responds to the commands of the golf cart driver, incorporating the speed direction that is too high by transmitting the magnitude of the individual current. Of armature and magnetic field coils and detecting when the current in the armature wire is opposite to the original direction The size of the coil current Armature depends on the opposite direction. Which is compared with the value That are pre-selected And an excessively high speed signal will be produced when The size of the opposite current is greater The preset value then the magnetic field current is controlled in such a way that it responds to an excessively high speed signal to limit the speed of the golf cart. To inhibit the conditions of the speed that are too high In addition, the voltage at the armature winding in the motor is monitored during During the period when the motor is in a non-powered state and the engine Shows the motion signal of the rotation of the armature motor. Was made available On the detection of the armature winding motor voltage, the magnetic field in the motor is energized. In a manner that responds to Polarity voltage motion signal for producing magnetic field to cause motor The symptom is a flow machine. Electricity and current are produced by the armature motor which is circulated through a pushing diode and into the armature motor for rotational damping. The electric arm of the armature motor with push brakes.
