Abstract
A two-speed motor is mounted in a housing with an end cap. The end cap has a tubular structure defining an interior space, including an open first end connectable to the motor casing. The second end includes at least one planar surface and at least one air grate configured to permit airflow into and/or out of the interior space. A dual speed pump controller includes a motor controller for operating the dual speed motor. The controller includes an operating speed circuit for operating the motor in one of a first speed or a second speed, the first speed being greater than the second speed; an event circuit for operating the motor at the first speed before a predetermined event and operating the pump at the second speed after the predetermined event.
Claims20
A motor assembly, comprising:
- a housing having an interior with a first portion and a second portion;
- a motor mounted within the first portion of the housing and not the second portion, the motor constructed and adapted to operate within the first portion at more than one speed, and a motor controller adapted to control operation of the motor, electrically coupled to the motor, and mounted within the second portion of the housing and not the first portion, the second portion of the housing including an air flow opening structure to permit air flow communication into and out of the second portion;
- the motor controller including an operating speed circuit configured or programmed to automatically cause the motor to operate at more than one speed, based on the occurrence of a selected event;
- the motor, air flow opening structure and housing adapted and configured to generate a directional air flow within the second portion of the housing as the motor operates, wherein the housing is configured so that the directional airflow generated by operating the motor will flow into the second portion of the interior, past the motor controller, then out of the interior.
A method of operating a motor connected to a pump and a motor controller, comprising the steps of:
- activating a motor constructed and adapted to operate at more than one speed in a first portion of a housing, the motor controller electrically coupled to a motor controller in a second portion of the housing, the motor operating a pump, the motor controller configured to automatically cause the motor to operate at a first speed and a second speed that is slower than the first speed, without input from a user;
- operating the motor and pump at the first speed for a pre-set amount of time, the operating motor causing air to flow from outside the housing, into the second portion of the housing, over the controller;
- and then out of the second portion;
- after the expiration of the pre-set amount of time, automatically switching the speed of the motor by the controller to the second speed.
A method of operating a motor connected to a pump and a controller, comprising the steps of:
- providing a motor in a first portion of a housing and a motor controller in a second portion of the housing, the motor operatively coupled to a pump and the motor controller configured or programmed to automatically cause the motor to operate at a first speed until a pre-set pressure level is detected at the pump outlet and then to cause the motor to operate at a second speed, slower than the first speed after the pre-set pressure level is detected;
- receiving pressure data at the controller, indicating an output pressure of the pump;
- operating the motor at the first speed, causing air to flow from outside the housing, into the second portion and out of the second portion until the controller receives a signal indicating that the pre-set pressure level is reached, then the controller automatically causing the motor to operate at the second speed without a user affecting the speed.
