Systems employed for motion control are called (a)  

(a)   an initial source of motive power designed to receive and modify force and motion applied by some natural source to drive machinery.

(a)   energy requirement for the operation of the system

Regulate the power flow from source to the motor

(a)  

An electrical machine that converts electrical energy into mechanical energy

(a)  

(a)   usually a machinery to accomplish a given task.

Adjusts motor and load characteristics for optimal mode.

(a)  

When a power modulator performs the function of electrical energy conversion, it can be classified as a converter

(a)  

Variable resistors are used for the control of low cost DC and AC drives and are also needed for dynamic braking of drives

(a)  

Switching operations in motor’s power circuit are carried out by high power electromagnetic relays known as contactor

(a)  

(a)   is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy

The burden placed on the motor due to this mechanical activity is referred to as the (a)  

When the torque of the motor and load is equal the drive is said to be at (a)  

Amount of rotational force that the motor develops

(a)  

Rate at which the motor rotates

(a)  

Quantitative measure of the rotational inertia of a motor

(a)  

Mode of the motor wherein the torque and speed developed are both positive.

(a)  

Mode of the motor where it works as a generator converting mechanical energy to electrical energy.

(a)  

It is powered by magnetism and used to open and close the contacts in the motor control circuit

(a)  

Opens the circuit in the event of an electrical, thermal or power overload

(a)  

Physically linked to the main contacts of magnetic contactor and activated at the same time.

(a)  

This is when a phased wire unintentionally touches a ground phase, such as a metal rail in a garage. This creates a path to ground from the phased wire. Again, the same problem occurs as the phase to phase short and can potentially cause fire.

(a)  

This is when one phase goes into another (two phases with no insulation accidentally touch each other). They create an unrestricted path for current to flow and a huge amount of current goes through them very quickly. This heats up the wire and burns down the insulation. Needless to say, the heat burning down the insulation can potentially cause fire

(a)  

Opens the contact point of a control circuit.

(a)  

This type of protection protects against short circuits. Similar to a contactor, the inside of a molded circuit breaker also has a coil of wire wrapped around a metal core

(a)  

This type of protection protects against overload/overcurrent. There are two thin strips of metal bonded together (bi-metal) and a trip bar next to it. Here’s a little theory: we know that metal expands when it gets warm.This type of protection protects against overload/overcurrent. There are two thin strips of metal bonded together (bi-metal) and a trip bar next to it. Here’s a little theory: we know that metal expands when it gets warm.

(a)  

This type of protection does not have thermal protection in order to ignore the Inrush in motors.

(a)  

Standard that gives the maximum operating temperature for each thermal class.

(a)  

Maximum permissible hot spot temperature of a winding.

(a)  

Ensure the motor driving the load reaches full speed quickly enough to avoid tripping the overload protection. Conversely, some loads require time to accelerate to full speed, e.g

(a)  

Temperature of the air surrounding the motor

(a)  

Indication of the ability to exceed the mechanical power output rating on a sustained basis

(a)  

Selecting a motor with higher horsepower than the required load application

(a)  

(a)   is an electrical machine that transforms electrical energy into mechanical energy by creating a magnetic field that is powered by direct current. When a DC motor is powered, a magnetic field is created in its stator

The motor has separate electrical supplies to the armature winding and field winding, which are electrically separate from each other.

(a)  

Uses permanent magnet and have excellent starting torque capability with good speed regulation

(a)  

(a)   the field winding is connected either in series or in parallel or partly in series, partly in parallel to the armature winding.

(a)   the field windings are exposed to the entire terminal voltage as they are connected in parallel to the armature winding

(a)   the field is connected in series with the armature

(a)   have both series and shunt field windings. These types of motors offer good starting torque, but they may have control problems in variable speed drive applications.

If the shunt field winding is only parallel to the armature winding and not the series field winding then its known as

(a)  

If the shunt field winding is parallel to both the armature winding and the series field winding then it’s known as long shunt type compounded wound DC motor or simply long shunt DC motor.

(a)  

(a)   is an electric motor driven by an alternating current (AC). An AC motor or alternating current motor commonly consists of a stator with a coil that is supplied with alternating current to convert electric current into mechanical power

(a)   used where there is a single phase supply. This type of AC motor is smaller and less expensive. They are constructed using fractional kilowatt capacity. The stator is activated by a single phase AC electrical supply.

(a)   or many phase motors, are a type of AC motor that can be two or three phase and are similar to single phase motors in how they operate.

(a)   is where the rotation of the shaft is at the same frequency as the current supply with the rotation period being equal to the integral number of AC cycles.

(a)   are a single phase motor, which operate with an accurate value of rotating magnetic field without any synchronous speed

The unique nature of the rotor of a (a)   is what makes it different from other AC motors. The rotor contains semi-permanent magnetic material.

An (a)   uses an induced current in its rotor to produce rotatory motion. This is the most common of the AC motors since it relies on AC current that is connected to the stator for its power supply
