Common current values are 5400 rpm, 7200 rpm, and 10000 rpm. However, these are not the only possible values.
Magnetic HARD Disk Drive constitutes of a Disk Platter, Spindle Motor, Read Write Head, Logic Card and Metal Casing with connector.

Common current values are 5400 rpm, 7200 rpm, and 10000 rpm. However 3600 rpm was very common for a number of years.
In an electromagnet, the drive shaft is turned by the interaction between the magnetic field produced by the electromagnet and a rotor that is typically mounted on the shaft. When electrical current flows through the coil of the electromagnet, it creates a magnetic field that attracts or repels the rotor. This magnetic force causes the rotor to rotate, thereby turning the drive shaft. The precise movement can be controlled by varying the current, allowing for adjustable torque and speed.
Using a drive plate on a lathe requires removing the chuck and the drive plate is attached in its place onto the spindle.
Torque specs for 2006 F-150 (2 wheel drive) spindle nut is 295 ft lbs. This is according to Ford's specs.

Spindle speed is very important. Don't accept less than a 7200 RPM spindle speed.
Yes. The magnetic 'platters' that store the information are arranged horizontally and are 'read' by an arm that swings over them. Think of an album on a turntable with the needle arm and you have a picture of one single set of such devices. Each drive is comprised of many sets of these in tight alignment, held in place by a spindle. The arm is held to tight tolerances and does not touch the platter but can read and write data to it by changing the magnetic state of the 'bits' on the platter. The density of the bits and the speed of the platter determine size of the drive (capacity) and it's cost.
Power is transferred from the drill spindle to the drill shank through the rotation of the spindle, which is connected to the motor. As the spindle rotates, it drives the drill bit, which is inserted into the drill shank. The force and torque generated by the spinning spindle are then transmitted through the drill bit to the workpiece, allowing for drilling to occur.
