Motor controllers

Article-Motor controllers

The RSH Series of soft start/stop motor controllers is said to be available in two sizes with basic rotary or advanced pushbutton controls. The co. says motor control capacity ranges from 1½ Hp at 220VAC to 40 Hp at 600VAC, adding that soft start/stop enables starting and stopping of 3-phase asynchronous with a simple 3-wire connection. Improved starting conditions reportedly result by suppressing in-rush currents during motor starting by gradually increasing torque from a user-preset point to a 100-percent level.
