Abstract: When a lock detector detects a locked state of a DC motor in a starting stage, a torque increasing circuit immediately selects a starting sequence pattern of an output torque that is greater in magnitude by one preselected step, and outputs the selected output torque to a starting sequence controller, so that a compressor can be restarted speedily without repeating starting failures. A compressor, driven by a DC motor, has a shell of an internal pressure approximately equal to the pressure of an inhalation gas. An inverter is provided to make the speed of the DC motor variable. A rotational frequency setting circuit sets the rotational frequency of the DC motor to a frequency that is not greater than the frequency of a commercial power source when the internal temperature of a refrigerator is stabilized. By this construction, the power consumption can be remarkably reduced.

Abstract: The present invention solves a problem that a power controller be large in a refrigerating system, and provides a compact-size as well as an inexpensive power controller. Highly heat-dissipating first board 1 including an inverter circuit mounted thereon and second board including a control circuit mounted thereon are placed in parallel with each other and accommodated by case 9. Case 9 has slits through which heat sink 2 and connector 6 can extend outside case 9, and further has fixing section 11 for fixing case 9 to a compressor. This structure allows the power controller to dissipate heat in an optimum manner and to be downsized, and also allows the compressor to integrate the controller thereinto. A capacity that the controller occupies in the refrigerating system can be substantially reduced.

Abstract: Cuando los mecanismos detectores 17 detectan un estado bloqueado del motor DC 4 en la etapa de arranque, los mecanismos de aumento del torque 18, 27, 29o 31, inmediatamente seleccionan un patron de secuencia de arranque de un torque de salida que es mayor por un paso, lo emiten a los mecanismos para el control de la secuencia de arranque 13, de manera tal que se puede volver a arrancar el compresor 5 rápidamente sin repetir las fallas de arranque. El compresor 41, accionado por el motor DC 43, tiene una estructura de una presion interna aproximadamente igual a la presion de un gas de inhalacion. Se proporciona un inversor 53 para hacer variable la velocidad del motor DC 43. Un circuito para establecer la frecuencia de rotacion 56 establece la frecuencia de rotacion del motor DC 43 a una frecuencia no mayor que la frecuencia de la fuente de energía comercial cual la temperatura interna del refrigerador se estabiliza. Por medio de esta construccion, se puede reducir de forma remarcable el consumo de energía.
