Abstract: A server for a control system for cooling systems is disclosed. The server includes a memory device configured to store instructions and a processor communicatively coupled to the memory device and a plurality of cooling systems. Each of cooling systems includes a motor, a sensor, a local memory, and a microprocessor communicatively coupled to the motor, the sensor, the local memory. The microprocessor is configured to control operation of the motor according to settings defined by configuration data stored in the local memory. In response to reading the instructions, the processor is configured to receive, from the sensor of each of the cooling systems, first sensor data, generate first configuration data by executing a first algorithm on the first sensor data, and instruct the microprocessor of at least one cooling system to write the first configuration data to the local memory of the at least one cooling system.

Abstract: An electric blower system is described. The blower system includes a blower, an airflow system, a sensor, and an electric motor. The electric motor includes a motor controller. The motor controller is configured to operate the motor at a first torque and a first speed to generate a first airflow, determine a first airflow value wherein the first airflow value, the first torque, and the first speed define a first benchmark data point. The motor controller is also configured to operate the motor at a second torque and a second speed to generate a second airflow and determine a second airflow value wherein the second airflow value, the second torque, and the second speed define a second benchmark data point. The motor controller is further configured to generate an operating profile for the blower system defining torque, speed, and airflow points for different system resistances.

Abstract: A blower has a blower housing of clamshell construction, including two housing members having a scroll back wall molded with radial draft, an impeller and a motor within the housing, and a static tap connected to the housing. The impeller has a backplate with a backplate back surface region of substantially the same radially converging shape as that of a front surface region of the scroll back wall formed by the radial draft, providing a substantially uniform axial gap between the backplate back surface region and the scroll back wall. The impeller has a ring connected by a skirt to the back plate to define a stepped area behind the ring. The impeller includes impeller blades extending forwardly from the impeller backplate and the ring and back fins extending rearwardly from the ring. The blower has a scroll width of about twice an impeller exhaust width.

Abstract: A blower includes an impeller housing, an impeller rotatably secured to the housing and an electric motor. The motor has a motor housing with a central portion and a radially extending portion extending from the central portion, a venturi chamber adjacent the motor housing and opposed to the impeller housing, a stator secured to the central portion of the motor housing, a rotor rotatably secured to the central portion of the housing, and at least one heat generating electrical component secured to the radially extending portion of the motor housing. The impeller housing has a first air pressure therein and the motor housing has a second air pressure therein different that the first air pressure. The venturi housing and the motor housing define a passageway therebetween whereby the difference in air pressure generates air flow within the motor housing to cool the at least one heat generating electrical component.

Abstract: A method of assembling an electric motor includes coupling a rotor hub to a rotor disk to form a rotor assembly and slidably coupling the rotor hub to a shaft at a first position. The method also includes coupling a stator assembly to the shaft to define a first axial gap between the stator assembly and the rotor assembly. The method further includes sliding the rotor assembly to a second position along the shaft to define a second axial gap between the stator assembly and the rotor assembly. The second position is based on a measured back EMF constant of the electric motor when the rotor assembly is in the second position.

Abstract: A circuit for detecting a status of a ground connection in an electric motor includes a rectifier, a converter, a voltage conditioning circuit, a leakage circuit, and a comparator. The rectifier couples to an AC line within the motor and generates a first DC voltage. The converter steps-down the first DC voltage to a second DC voltage. The voltage conditioning circuit couples to the converter, leakage circuit, and comparator, and generates a reference DC voltage signal and a leakage voltage from the second DC voltage. The leakage circuit includes an impedance coupled to ground, and applies the leakage voltage to the impedance and generates a measurement signal representing a leakage current through the impedance to ground. The comparator couples to the leakage circuit and generates a logic signal, indicating a status of the ground connection, based on a voltage difference between the reference DC voltage signal and the measurement signal.
