Three types of power converters viz., uncontrolled, half controlled and full controlled are used in adjustable DC drives.
Slip power is the electrical power that is converted into mechanical power due to the slip between the stator magnetic field and rotor in an induction motor. It is the power required to maintain the rotor's rotation at a speed slightly lower than the synchronous speed of the stator field.
Watts is a measure of power and is not directly related to speed. However there is a connection between power and speed in moving vehicles where the mechanical power required to drive the vehicle along is proportional to the cube of the speed (approximately). So if a car requires 100 HP to travel at 100 mph, it would require about 70 HP to go at 90 mph.
frequency of the power supply it is connected to. The speed of a single phase motor is directly related to the frequency of the alternating current (AC) power supply. As the frequency of the power supply changes, the speed of the motor will also change.
The most energy-saving ceiling fans with lights are those that are ENERGY STAR certified, use LED bulbs, and have a DC motor for increased efficiency. Look for fans with variable speed settings and a reversible motor to maximize energy savings.
Motor shaft speed refers to the rotational speed of the motor's output shaft in revolutions per minute (RPM). It indicates how fast the motor is rotating and is a key parameter in determining the mechanical power output of the motor. Motor shaft speed is influenced by the frequency of the electrical power supplied to the motor and the motor's design specifications.

A variable-frequency drive (VFD) is a system for controlling the speed of a rotational or linear alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.[1][2][3] A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives.

Frequency drives are an adjustable-speed drive used for electro-mechanical drive systems. They control the motor speed and torque by varying motor input frequency and voltage.
