ELECTROLYTIC STARTER

PRINCIPLE

Thanks to the VECTROSTAR R principle, the user obtains the maximum torque at very low speed (starting of locked and loaded machines can be accomplished). Start-up current for slip-ring motors from 0,5 to 1,5 rated current in.

PERFORMANCES

• Drastic decrease in start-up overcurrent.
• Adjustement of maximum torque with minimum current.
• Suppression of mechanical shocks through a constant acceleration torque and progressive speed increase.
• Enables a number of start-ups in a row without any possible damage to the resistivity.
• Suitable for a wide range of motors allowing motor and machines changes

ADVANTAGES – SMOOTHESS

The continuous and controlled decrease in rotor resistance provides start-ups without mechanical snatches.

ADAPTABILITY

The dosage of the electrolyte allows a perfect adaptation of VECTROSTAR R to the operating environment of the motor (resistant torque, inertia, load, etc…). The duration of the start-up depends on the dosage of the electrolyte, as well as on the adjustment of the flow valve which controls the electrolyte flow entering the start-up tank.

CONSISTENCY

The electrolyte reserve tank is large enough to allow an efficient circulation into the start-up upper tank. Subsequent start-ups can be made without changing their characteristics.

SECURITY

The VECTROSTAR R envelope provides an electrical insulation, except for Vectrostar from R 1500 up to R 4000 which have to be earth connected).
A thermostat monitors the electrolyte temperature inside the start-up tanks.

ROBUSTNESS

IP 569 protection, corrosion resistant equipment, limited maintenance is required. The starters from Vectrostar R 1500 to R 4000 are built in stainless stell. 5AISI 304L as a standard).

RELIABILITY AND MAINTENANCE

• Low operating temperature minimizes electrolytic fluid maintenance.
• Anti-corrosive electrodes eliminate oxidation and breakage.
• Unit can be installed in any location. Harsh environments are not a problem.
• Standard unit controls permit full automation of start-ups.

ECONOMICAL

Installation flexibility and low maintenance make the VECTROSTAR very economical.
