Control device for controlling the power supply to an oscillating motor for driving a compressor unit of the resonant-piston type and compressor unit of the resonant-piston type provided with such a control device
A control device (30) is disclosed for controlling the power supply to the coils (16A, 16B) of a drive motor (3) for a compressor unit of the resonant-piston type (1). The control device comprises a power-supply circuit (44) for energising the motor coils (16A, 16B) from a direct voltage source (45)...

Summary: | A control device (30) is disclosed for controlling the power supply to the coils (16A, 16B) of a drive motor (3) for a compressor unit of the resonant-piston type (1). The control device comprises a power-supply circuit (44) for energising the motor coils (16A, 16B) from a direct voltage source (45), means (46, 47, 48; 46, 60) for determining a measure (P, phi ), which indicate whether the power consumption of the motor as a function of the frequency of the energising current is at least approximately maximal, and means (40, 42, 43; 61, 42, 43) for adjusting the frequency of the energising current depending on the derived measure (P, phi ) to a value for which said measure (P, phi ) indicates that the power consumption of the motor (3) is maximal. |
