Speed decreases as gear ratio increases.

• Increasing the gear ratio means the output gear has more teeth than the input gear.

• This results in a decrease in speed and an increase in torque.

• For example, if the gear ratio is 2:1, the output gear will rotate at half the speed of the input gear.

PPR stands for Pages Per Minute and is a measure of the printing speed of a printer.

• PPR is a common metric used to compare the printing speed of different printers.

• It indicates the number of pages a printer can print in one minute.

• Higher PPR values indicate faster printing speeds.

• For example, a printer with a PPR of 30 can print 30 pages in one minute.

IGBT stands for Insulated Gate Bipolar Transistor. MOV is Metal Oxide Varistor. They are used for different purposes.

• IGBT is a type of power semiconductor device used for switching applications in power electronics.

• It combines the advantages of both bipolar junction transistors (BJTs) and metal-oxide-semiconductor field-effect transistors (MOSFETs).

• IGBTs are commonly used in applications such as motor drives, power supplies, renewable energy systems, and electric vehicles.

• MOV...read more

AC drives are devices used to control the speed and torque of electric motors.

• AC drives, also known as variable frequency drives (VFDs), convert fixed frequency AC power to variable frequency power to control motor speed.

• They are commonly used in industrial applications to save energy, improve motor performance, and enable precise control.

• AC drives consist of a rectifier, DC link, and inverter, which work together to convert and control the power supplied to the motor.

• They ca...read more
