Which of the following motors is most suitable for signalling devices and many kinds of timers?

Which of the following motors is most suitable for signalling devices and many kinds of timers? Correct Answer Reluctance motor

A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. The rotor does not have any windings. Torque is generated through the phenomenon of magnetic reluctance.

Reluctance motors can deliver very high-power density at low cost, making them ideal for timing devices and control apparatus. The other applications of reluctance motor are,

  • Signalling devices
  • Recording instruments
  • Phonographs
  • Analog electric meters

Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. What inference can be drawn from the above?
