Linear electrodynamic motor, cryogenic cooler comprising such a motor and method using such a motor

The motor (4) has switching devices e.g. switches (21, 22), selectively connecting secondary circuits (14-1, 14-2) to induction coils (5-1, 5-2). Each switching device occupies first and second positions in which the secondary circuits are connected and disconnected from the coils. Power-supply circ...

Beschreibung
Zusammenfassung:	The motor (4) has switching devices e.g. switches (21, 22), selectively connecting secondary circuits (14-1, 14-2) to induction coils (5-1, 5-2). Each switching device occupies first and second positions in which the secondary circuits are connected and disconnected from the coils. Power-supply circuits (8-1, 8-2) are disconnected from the coils when the secondary circuits are in the first position. The power-supply circuits are connected to the coils when the secondary circuits are in the second position. Each secondary circuit is provided with a compensation component. The compensation component is formed of resistors (R1, R2) and capacitors (C1, C2). Independent claims are also included for the following: (1) a Stirling cycle cryocooler (2) a method for compressing fluid circulating in a Stirling cycle cryocooler.
