The internal mechanism of an elevator is much complex. There are many kinds of elevators and each one has its unique inner machinery. These are the 3 most common kinds of elevator motors:
AC motor(commercial/residential): Typically used in commercial as well as residential settings, but they normally use a higher voltage as compared to your home electricity
Diesel/gasoline powered motor: Employed when electricity is out of stock
Pneumatic/hydraulic actuators: These are typically used for very heavy loading as well as low-rises, such as in car repair shops or else for cargo lifts.
Types of Motors
Traction elevators are operated by means of a counterweight that balances the weight of the cab along with its passengers.
Geared traction elevators are regulated or “driven” by AC or else DC electric motors.
For a machine room less traction lift, a smaller gearless traction motor is compulsory.
Hydraulic elevators also make use of electric motors, as well as these elevators are powered through a piston that travels within a cylinder. The electric motor forces hydraulic oil into the cylinder which shifts the piston, then the piston effortlessly lifts the elevator cab.
