Page 4: Introduction
JL/X130 - 1680 2 Introduction A slip ring motor is a type of induction motor having a wound rotor connected to slip rings. The stator (U, V, W) is phase angle controlled by the JL/X in a closed loop with speed feedback derived from a tacho generator or encoder mounted on the motor shaft. -
Page 5: Operation Of Slip Ring Motor
JL/X130 - 1680 2.1 Operation of Slip Ring Motor 2.1.1 Stator Voltage Control The Speed / Torque curve for a Slip Ring Motor is shown in the diagram below for the case where the Rotor resistors are static. The curved lines represent the Speed / Torque relationship at 100% and 80% Stator voltage. -
Page 6: Rotor Control To Optimise Torque Across Speed Range
JL/X130 - 1680 2.1.3 Rotor Control to optimise torque across speed range The diagram shows all 4 quadrants of Speed against Torque, with curves for a shorted rotor and for 4 other values of rotor resistance. This diagram is of course a simplistic representation to facilitate the explanation of the control strategy. -
Page 7: Hyper-Synchronous Regeneration
JL/X130 - 1680 2.1.4 Hyper-synchronous regeneration The shaded areas in the braking quadrants are where regeneration can occur. Outside the shaded areas any braking that occurs is achieved through a process known as plugging in which the absorbed energy is dissipated in the rotor and the rotor resistors. -

JL/X130 - 1680 2.2 Control terminal default functions When the JL/X is shipped the control terminals are allocated with the following functions. All the programmable terminals are available to be re-allocated to an alternative function by the user if desired. IMPORTANT WARNING: The JL/X default configuration is locked in recipe page 3. -

JL/X130 - 1680 When tightening the connecting bolts of the terminals L1/2/3 A+ A- please ensure that the busbar is not subjected to a turning moment as the nut is torqued down. To do this always use two spanners, one on the bolt head to provide a counter torque and one on the nut to provide tightening torque. - Page 27 JL/X130 - 1680 Oct 2010 HG103521issh...
