What is a spindle drive?

What is a spindle drive?

(OP)
I'm not english and can't understand accurately this item, is it an axe controller? Thanks.

RE: What is a spindle drive?

I believe you are refering to the drive control unit for a spindle motor.  On some machines the motor direct drives a small gearbox and then performs an output function.  The drive or "inverter" is used to control this motion of the motor.

RE: What is a spindle drive?

A spindle drive has a torque/speed performance as follows:

Constant torque from 0rpm to a base speed and constant power output above this speed.

Example,
0rpm to 1500rpm with 10Nm and above 1500rpm the power output (1.5kW) is constant to 6000rpm. So at 6000rpm the torque is 2.5NM. (Power output is approx = rpm/10 * Nm)

A typical application is to drill holes. Often 20,000rpm is the top speed and 3 phase asynchronous motors are used with a frequency inverter (up to 600Hz)

Special spindles are used in servo applications (C- axis) that can rotate smoothly from 1rpm to the base speed.

RE: What is a spindle drive?

Rotary to linear conversion. Nothing more. A motor performs a rotary motion(!) we need to sometimes drive robot arms in a 'linear' fashion.
Pretty much old hat in Robotics. ABB S2 robots used them but dropped them for far better planetary drives.
http://www.roboknowledge.com has some stuff on S2 . You might want to post there.

In the data storage industry (magnetic, optical disk etc,)
the motor/disk assembly is usually called spindle
