If more than one drive is being operated from the power supply this is not a problem since the other drive(s) will absorb this current for its needs, unless it is decelerating as well. For this case or for a single drive it may be necessary to place a voltage clamp across the power supply in the form of a Zener diode. The voltage of this diode must be greater than the maximum expected power supply voltage, yet low enough to protect the drive. A good choice would be either 82 volts or 91 volts as standard values.

What comes with the increased motor power with increased power supply voltage is increased motor heating; this heating increases more rapidly than output power and ultimately sets the maximum output power from the motor. That is to say, the limiting factor in how much power a motor can deliver is ultimately determined by how much heat it can safely dissipate.

The purpose of impedance is to generalize the idea of resistance to create a component. To capture the behavior of resistors, capacitors, and inductors, for steadystate sinusoidal signals. This generalization is motivated by the fact that as long as the circuit is linear, its behavior can be analyzed using KVL and KCL.

We mentioned a catch, earlier. With these and other motor wiring variations possible, it’s easy to make a mistake. That drawing we said to follow could be wrong. Before you connect any wires, check the drawing carefully. That’s another reason to have that pocket motor wiring guide.

While resistance of a circuit is the instantaneous ratio between voltage and current, impedance of a circuit is the ratio between voltage and current for steady-state sinusoidal signals, which can vary with of frequency. As the later parts of this section will show, the voltage and current caused by applying a steady-state sinusoidal signal to any combination of resistors, capacitors, and inductors, are related by a constant factor and a phase shift. Therefore, impedance can be expressed by a complex constant using an extended version Ohm’s law.

The ratio between voltage and current is known as resistance. For most metallic conductors, the relationship between voltage and current is linear.

While electrical is the basis of everything, electronic is a subset of electrical. An electrical circuit deals with just the flow of electrons and has components like resistors, inductors and capacitors and uses Alternating Current Source; while electronic circuit deals with the transformation of current and controlling the motion of the electrons and uses Direct Current Source. An electrical circuit is termed as Passive because it doesn’t have any such component that reacts to the current/voltage that passes through them and electronic circuit is called active because of the additional components like diode or a transformer that react to the current/voltage that passes through.

In this sort of a connection all the components would receive the same voltage, while the current would be divided amongst the components.
