1 Description

1.1 Design and Function

The TURBOTRONIK NT 340 M, NT 340 MA, and NT 341

MA are electronic frequency converters. They operate

turbomolecular pumps TURBOVAC.

The TURBOTRONIK NT 340 MA and NT 341 MA are

prepared for operation with an additional temperature

control unit. This temperature control unit is part of a

temperature control which maintains the temperature of

the TURBOVAC within a narrow control range.

The TURBOTRONIK converts the single-phase mains

voltage into a regulated DC power supply. The unit’s

electronic circuitry then switches this DC power supply

onto the four stator windings of the TURBOVAC’s com-

mutatorless DC motor in a cyclical sequence.

This electronic switching system uses Hall probes, and

replaces the commutator normally found in DC motors. A

digital controller keeps the speed of the motor constant.

The TURBOTRONIK also powers and regulates the

magnetic bearing unit. Switching the motor to the gen-

erator mode keeps the magnetic bearing unit in operati-

on even in case of a mains power failure.

Both the TURBOTRONIK and the TURBOVAC are fitted

with sensors to ensure reliable operation of the entire

system. External control and monitoring equipment e.g.

the LEYBOTRONIK I can be connected via floating plug-

and-socket terminals located at the rear of the TUR-

BOTRONIK. Both the remote control unit and the lines

for the pump system’s status signals are connected here.

These terminals also provide connections for controlling

the forepump, the heater and valves.

An RS-232 interface provides a further control and mon-

itoring option.

The unit also has a counter-current braking system for

slowing down the pump when it is shut down.
