None: "high tension" is just another way of saying "high voltage".
It depends on ampage & voltage of the motors involved.
ac voltage
Basically anything that works with batteries usually works with DC motors, i.g. your hard drive, your cellphone vibrator, toys, etc. Also, even for large motors, the DC motor has the advantage of being easily controlled by input voltage. Induction motors, on the other hand, can use controlled input voltage but they will have to deal wth low torque when the voltage is low. DC motors are used for those little fans in your computer. Also, CD players also use DC motors to spin the discs. DC motors are important where absolute speed control and feedback are necessary. For your household appliances, including fan motors, those are AC motors, cheaper for the industrial strength and more efficient.
On some motor nameplates you may see 120/208-240. These are not true tri-voltage motors. They are dual voltage motors with a leniency on the 240 volt range to be derated to run on 208 volts. At this voltage the current drops and you don't get the full horse power rating of the motor. To answer your question I have never seen one that would do true three voltages like 120/240/480.

These types of motors are classified as dual voltage motors. The highest motor voltage rating is always double the lowest voltage rating. Dual voltage motors are more versatile in matching the system voltage supply that they are connected to. When the motor uses the highest voltage rating the coil legs are in series, dropping the high voltage across two coils. When the motor is connected to the low voltage rating the coils are connected in parallel dropping the low voltage rating across the two coils in parallel. As you can see no matter which configuration that you use the individual coils can never get a voltage across them greater than the lowest of the two voltages available. The connection diagram is usually on the underside of the motor's junction box lid.
there are low-voltage electrical appliances, enameled wires for micro-motors for automobiles, and enameled wires for computer monitors.

Veo produces: turbine generators, the VEDA 500 low-voltage switchgears, marine generators, thrusters and prime mover motors and transformer stations.
There are three main categories of low voltage. It depends on what type of system the voltage belongs to, as each system has a bottom end or low voltage assigned to it.
Transformers are used to convert electricity from high voltage to low voltage and from low voltage to high voltage.

A normal motor run at a fixed speed depending on: AC motors: Voltage and frequency (Hetz) and number of poles DC Motors: Armature voltage Stepper motors speed depend on the drive pulse frequency.
Low voltage by definition means any voltage from 31 to 750 volts inclusive.
