 RLV vapormatic starters are used when the driven machines are of great inertia or when the rating power of starting / driven machine is low. They have the following advantages


  • No moving parts other than the short circuit contactor
  • Unaffected by damp, dusty or corrosive atmospheres


  • Cable saving: integral contactors
  • Facilitate installation beside motors
  • Electrical and mechanical maintenance considerably reduced
  • Competitive price


  • Easy adjustment gives "made to measure" starting conditions and conversion to suit different drives.

Operating principle

The starting principle is based on the difference in resistivity between a liquid electrolyte and its vapour, contained in an electrode chamber.

The passage of the initial rotor current causes immediate partial vaporisation of the electrolyte and instantaneously adjusts resistance and starting torque to optimum values. During the run-up to speed, the thermal interchanges which occur progressively decrease the resistance.

A timed contactor then short circuits the low residual resistance.

The starting torque is determined according to the requirements of the driven machine or the current limitation.

Rotor voltage between slip rings:

– M15 / M35 / M70: 750 V

– M350: 1500 V

Further features

Electrolyte Composition : In powder or crystal form for mixing with drinking water and anti-evaporation oil

Electrolyte temperature is controlled by thermostat:

– M15 / M35 / M70: 10 A / 220 V, 8 A / 380 V or 5 A / 500 V 

– M350: 9 A / 380 V

Electrolyte level:

– M15 / M35 / M70: By filler pipe 

– M350: By magnetically operated float switch (250 V – 60 VA) in each compartment
Electrode assembly The RLV “triphase” electrode assembly is a standard component.

The value of resistance is factory preset according to the data of the driven machine given by the customer at the order. It is always possible for him to make adjustments on site, either for a change of drive of for a different duty. This is easily carried out by changing the electrolyte and/or the size of the electrode chamber.
Rotor starter protection system On request we can supply your starter with an electronic module type DRS.

This module allows the following:

– locked rotor detection of your motor

– optimisation of the starting time by measuring the true speed of the motor

– temperature monitoring of the electrolyte

– limitation of the number of starts per hour

Any anomaly in the starting sequence is detected by a fault relay which can be connected to your control panel.
