Functional capabilities

The ELEKTON-SSC soft-start coupling facilitates the start of an electric submersible motor on ESP and PCP, and prevent the backspin effect.

Tpump, Tmotor – Pump shaft’s torque or ESP motor’s shaft torque, respectively	Starting currents without SSC Starting currents with SSC t – electric submersible pump starting time
n – ESP motor’s RPM, T – ESP motor's shaft torque	Tm.start – Starting torque from motor direct start Tm.critical – ESP motor critical torque Tm>p without SSC – Pump torque overcome by motor starting torque (without SSC) Tm>p with SSC – Pump torque overcome by motor torque with SSC ΔT – Torque increment on the motor›s shaft with SSC
