Abstract
A two-speed motor is stored in 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.
Claims19
A motor assembly, comprising:
- a housing having an interior containing a motor capable of operating at two speeds and a motor controller adapted to control operation of the motor, electrically coupled to the motor, and sealed within the interior of the housing;
- the motor controller including an operating speed circuit configured or programmed to automatically cause the motor to operate, without input from a user, in one of a first speed or a second speed, the first speed faster than the second speed;
- an event circuit, configured or programmed to automatically determine when a pre-set event occurs and automatically send a signal to the motor controller to indicate that the event has occurred;
- the motor controller configured or programmed to automatically control operation of the motor at the first speed before receiving the signal indicating that the event occurred and to automatically control operation of the motor at the second speed after receiving the signal indicating that the event occurred, without interference from a user.
A method of operating a motor connected to a pump and a motor controller, comprising the steps of:
- providing a motor and a motor controller in a sealed housing, the motor operatively coupled to a pump and electrically coupled to the motor controller, the motor controller configured or programmed to automatically cause the motor to operate at a first speed for a pre-set amount of time and at a second speed that is slower than the first speed after the pre-set amount of time, without input from a user;
- operating the motor at the first speed for the pre-set amount of time;
- and
- after the expiration of the pre-set amount of time, automatically switching the speed of the motor by the controller to the second speed, without a user affecting the speed of the motor.
A method of operating a motor connected to a pump and a controller, comprising the steps of:
- providing a motor and a motor controller in a sealed 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;
- receiving pressure data at the controller, indicating an output pressure of the pump;
- operating the motor at the first speed 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.
