Drives: Ideal Applications for WRIM and SRC

Secondary Resistive Controllers are used to drive Wound Rotor Induction Motors in a wide range of industries such as:

Conveyor starting:

• Long, controlled acceleration time
• Soft, smooth, repeatable

Crusher starting:

• Limited current inrush (limited to % applied torque)
• Breakdown torque available with multiple starting

Mill starting:

• Load sharing is simple
• Mill speed adjustment available

Variable speed slurry pumps, with minimal speed control:

• Can match SRC characteristics to pump curve to minimize electrical and mechanical losses, with high reliability

Miscellaneous applications:

• Reduced speed conveyor off-loading and creep function
• Automatic load sharing for tar sand characteristics
• Breakdown torque control for crushers
• Downhill regenerative conveyor applications
