In both directions.<\/p>\n<p>Ward Leonard control is a method of speed control for electric motors that uses a DC motor, a variable voltage DC power supply, and a controller. The DC motor is the load, and the variable voltage DC power supply is used to control the speed of the motor. The controller is used to regulate the voltage of the power supply, which in turn controls the speed of the motor.<\/p>\n<p>Ward Leonard control can be used to control the speed of a motor in both directions. To control the speed of the motor in the forward direction, the voltage of the power supply is increased. To control the speed of the motor in the reverse direction, the voltage of the power supply is decreased.<\/p>\n<p>The Ward Leonard control method is a versatile and efficient method of speed control for electric motors.
