Energy Stored in a Capacitor where there is a safety issue, larger values might need a discharge (bleed) resistor to control
Working of Sequential Motor Control Circuit. The working of a sequential motor control circuit is relatively simple. The control circuit first activates the first motor in the sequence by sending a signal to the associated starter, contactor and relay.Once the relay receives the signal, it switches on the power to the motor, causing it to start running.

To vary the voltage and control the speed of the motor, it will send this as pulses. Each pulse lasts a period of time, during this period there will be a segment when the signal is ON, so voltage is applied, and a segment where the signal is off, so no voltage is applied. This causes a very large and sudden surge in energy which can damage
During this operation, the motor controller is designed to recover the kinetic energy and store it in the battery or the capacitor banks. Regenerative braking helps in extending the range of the electric vehicle by 8-25%. Apart from saving energy and enhancing the range, it also helps in effective control of the braking operation.

More energy efficient circuits eliminate cylinder control valves altogether, where stored energy is not dissipated into heat. Circuits such as these are denominated pump-controlled actuators [or "hydrostatic actuators" ( Costa and Sepehri, 2015 )] and are a direct evolution from "hydrostatic transmissions," where a hydraulic motor is
So how do we control the flow of current through the motor. Well many people attempt to control the speed of a DC motor using a large variable resistor (Rheostat) in series with the motor as shown. While this may work, as it does with Scalextric slot car racing, it generates a lot of heat and wasted power in the resistance.
Motor branch circuits need protection from excessive temperatures due to overload, short-circuit, and ground-fault currents. The Informational Note to Section 240.1 states the overcurrent protection for conductors and equipment opens the circuit if the current attains a value that will cause a dangerous temperature in conductors or conductor insulation.

The circuit uses several accumulators to supplement pump flow because the dwell time is 45 sec. out of the 57.5-sec. cycle. Its 22-gpm fixed-volume pump operates on pressure during most of the cycle to fill the cylinder and accumulators. Without the accumulators, this circuit would require a 100-gpm pump driven by a 125-hp motor.
Sometimes this scheme is called the scalar control because it focuses only on the steady-state dynamic. Scalar control is a simpler form of motor control, using non-vector controlled drive schemes. An AC induction motor can be led to a steady state by simple voltage fed, current-controlled, or speed controlled schemes.
