The stators the stationary part magnetic field is produced by using either a wound stator field winding or by. Brushless Motor. Normal DC motors have almost linear characteristics with their speed of rotation being determined by the applied DC voltage and their output torque being determined by the current flowing through the motor windings. They are connected to and controlled by a PWM type controller and are mainly used in positional control systems and radio controlled models.

This type of motor is basically a brushed DC motor with some form of positional feedback control connected to the rotor shaft. Generally brushed DC motors are cheap. This type of motor produce a magnetic field in the rotor by using permanent magnets attached to it and commutation is achieved electronically.

By connecting them to gearboxes or gear-trains their output speed can be decreased while at the same time increasing the torque output of the motor at a high speed. Servo Motor. The speed of rotation of any DC motor can be varied from a few revolutions per minute rpm to many thousands of revolutions per minute making them suitable for electronic. A series wound DC motor has the stator field windings connected in series with the armature while a shunt wound DC motor has the stator field windings connected in parallel with the armature.

A conventional brushed DC Motor consist basically of two parts. The magnetic field setup by the rotor tries to align itself with the stationary stator field causing the rotor to rotate on its axis. The motors wound stator is an electromagnet which consists of electrical coils connected together in a circular configuration to produce a North-pole then a South-pole then a North-pole etc.

The commutator allows an electrical connection to be made via carbon brushes hence the name "Brushed" motor to an external power supply as the armature rotates. The rotor or armature of a DC machine consists of current carrying conductors connected together at one end to electrically isolated copper segments called the commutator.

The rotational speed of the motor is dependent on the strength of the rotors. The stators electromagnetic coils can be connected in series. By varying this applied DC voltage the rotational speed of the motor can also be varied. Samarium Cobolt. To overcome these disadvantages.

The control of the brushless DC motors is very different from the normal brushed DC motor. Although DC brushed motors are very efficient and cheap.

Then the construction of a brushless DC motor is very similar to the AC motor making it a true synchronous motor but one disadvantage is that it is more expensive than an equivalent "brushed" motor design. The design of the brushless motor eliminates the need for brushes by using a more complex drive circuit was the rotor magnetic field is a permanent magnet which is always in synchronization with the stator field allows for a more precise speed and torque control.

Brushless DC Motors were developed. Using the Hall sensors signals. Brushless DC motors can be constructed to have.

Then the motor can be easily synchronized to a digital clock signal. Electric machines without a transformer circuit topology. Always limited by magnetic core saturation or safe operating temperature rise and voltage. Some applications require bursts of torque beyond the maximum operating torque.

Induction Doubly-Fed electric machines. Magneto-MotiveForce or the product of current and winding-turns induced on either side of the transformer oppose each other and as a result.

Electric machines with a transformer circuit topology.

Robotic Trolley for Material Handling

Electric machines that rely on Induction or Asynchronous principles shortcircuit one port of the transformer circuit and as a result. The dual ported transformer circuit topology is known to be unstable and requires a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set.. The Synchronous WRDF electric machine is the only electric machine with a truly dual ported transformer circuit topology i. Torque bursts greater than eight times operating torque have been calculated.

If a precision means were available to instantaneously control torque angle and slip for synchronous operation during motoring or generating while simultaneously providing brushless power to the rotor winding set the active current of the Synchronous WRDF electric machine would be independent of the reactive impedance of the transformer circuit and bursts of torque significantly higher than the maximum operating torque and far beyond the practical capability of any other type of electric machine would be realizable..

Rechargeable batteries use electrochemical reactions that are electrically reversible. Commonly used secondary cell "rechargeable battery" chemistries are lead acid. Some rechargeable battery types are available in the same sizes as disposable types. For example. Proper selection of a rechargeable battery system can reduce toxic materials sent to landfills compared to an equivalent series of disposable batteries.

While the rechargeable cells have a higher initial cost. Rechargeable batteries come in many different sizes and use different combinations of chemicals. Rechargeable batteries can offer economic and environmental benefits compared to disposable batteries. Grid energy storage applications use industrial rechargeable batteries for load leveling.

By charging batteries during periods of low demand and returning energy to the grid during periods of high electrical demand.

Unlike non-rechargeable batteries primary cells. Emerging applications in hybrid electric vehicles and electric vehicles are driving the technology to reduce cost. The need to charge rechargeable batteries before use deterred potential downloaders who needed to use the batteries immediately. Most battery chargers can take several hours to charge a battery. These electrons constitute the current flow in the external circuit. Most batteries can be charged in far less time than the most common simple battery chargers are capable of.

The energy used to charge rechargeable batteries mostly comes from AC current mains electricity using an adapter unit. Duracell and Rayovac now sell chargers that can charge AA. The electrolyte may serve as a simple buffer for ion flow between the electrodes. Diagram of the charging of a secondary cell battery. Battery manufacturers' technical notes often refer to VPC.

Battery is susceptible to damage due to reverse charging if they are fully discharged. Most devices are designed to continue to operate at a reduced voltage of between 0. Fully integrated battery chargers that optimize the charging current are available. This is volts per cell.

Flow batteries. When one cell completely discharges ahead of the rest. This is commonly referred to as "cell reversal". Some Ni-Cad type cells exhibit a "memory" effect. Some Ni-Cad type cells that are not fully charged and discharged periodically can lose their ability to retain a full charge.
