liquid resistance starter
EPMA Liquid Resistance
Starters for Slip-ring motors. 200 to 20 000 kW.
The EPMA starter has been specifically designed by AOIP for controlled starting and speed control of large slip ring motors in arduous applications such as:
Crushing
Milling
Conveyors
Pumps
Ventilation
In a variety of industries such as mines, quarries, cement plants, water treatment and associated
Industries.
CSE-Uniserve Pty Limited has adapted this basic design under license to AOIP to suit the harsh conditions typical of Australian mining installations. The starter tanks are manufactured here in Australia from stainless steel to AS 1554, and customized to suit outdoor installation, with minimal maintenance requirements.
All Unistarter units are manufactured in Australia and in conformance with Australian Standards.
The EPMA rotor starter is used to control the starting of a slip ring
(wound rotor induction) motor. The starting current is generally limited to a maximum of 250% Full Load
Current. Optimal starting torque for each application is selected by the choice of the initial value of resistance. The principle of the liquid starter is that of a secondary resistance starter, where by the rotor resistance is reduced to a minimum during the starting period.
This type of starter is designed to provide the optimum starting characteristic, which results in smooth progressive acceleration to full load speed. It can also be used for speed variation and torque control. Plug braking can also be implemented with this system. The variation in the resistance is achieved by displacement of the electrodes in the electrolyte. At the end of the acceleration, the electrodes are shorted out.
