Abstract

An inverted planar motor employ a magnetic displacement device (10), and a coil actuator (20) magnetically interactive with the magnetic displacement device (10). The coil actuator (20) includes an electric coil (21) and a current amplifier (26) switchable between a K-factor measuring mode and a current measuring mode. The K-factor measuring mode includes current amplifier (26) preventing a flow of current through the electric coil (21) to facilitate a measurement of an electro motive force voltage (VEMF) indicative of a K- factor of the electric coil (21). The current measuring mode includes current amplifier (26) controlling a flow of current through the electric coil (21) and a current sensor (27) facilitating a measurement of the flow of current through the electric coil (21). The coil actuator (20) further includes a primary cooling body (25) having current sensor (27) disposed therein to stabilize a current measuring temperature of the current sensor (27).
