Patent ID: 7459900

Claim:
A modular current sensing system for a servo control system comprising: a magnetic core defining an open center portion; a connection plate including at least three wire connectors, including a first, a second, and a third wire connector, wherein each wire connector is capable of connecting at least two wires electrically in series and the first wire connector is electrically connected to a primary winding of a first motor; a plurality of wires, including: a first wire with a first end and a second end, wherein the first end of the first wire is electrically connected to a first power source, and the second end of the first wire is connected to the connection plate at the first wire connector and wherein the first wire passes through the open portion defined by the magnetic core at least once, the first wire thereby inducing a core current to flow in the magnetic core and causing the magnetic core to emit a magnetic field upon initiation of a first motor current flowing between the power source and the primary winding of the first motor; a second wire with a first end connected to the second wire connector and a second end connected to the third wire connector, and wherein the second wire passes through the open portion defined by the magnetic core at least once; a Hall effect sensor that detects the magnetic field, produces an output current, and delivers the output current to a control device within a servo control system; and wherein the first and second connectors are adapted to receive a splicing device to electrically connect the first and second connectors and cause the first and second wires when spliced to become one effective wire that wraps around the core in multiple places to produce multiple magnetic fields.
