Linear electrodynamic type motor, cryogenic cooler comprising said motor and procedure that carries out said motor

摘要

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.
