A method of calibrating a motor assembly includes selecting an electric motor and a motor controller for the motor assembly, obtaining at least one electric motor parameter of the electric motor, determining a correction factor for the electric motor based upon the at least one electric motor parameter, and programming the motor controller with the correction factor.

An integrated method for assessing metabolic rate and maintaining indoor air quality and efficient ventilation energy use. A physical sensor assesses room occupancy. An actuated ventilation system is set to a constant CO.sub.2 level in a predetermined healthy range, where the actuated ventilation system includes a CO.sub.2 sensor. The actuated ventilation system sets a first air ventilation rate and the sensor measures a first CO.sub.2 level. The system determines whether CO.sub.2 level is in a healthy range, if not then the CO.sub.2 level is adjusted by setting a subsequent air ventilation rate. A subsequent CO.sub.2 level is measured. If the CO.sub.2 level is determined to meet a predetermined healthy range, then an assessment of change of air ventilation rate (Δ ACH) is determined. The determination of air change rate can be further augmented by a physical pressure based measurement. The overall metabolic rate is generated.

A motor control apparatus may relate to a motor control apparatus, an air conditioning system, and a constant airflow control method of a fan motor control apparatus of an indoor unit, in which table information on an airflow command value corresponding to a reception pattern or type of a signal is prestored to determine a corresponding airflow command value from the table information according to a result of receiving the signal from a central control apparatus so as to control an operation of a fan motor.

A motor control system providing at least seventeen speed settings using industry standard control signals and an industry standard five pin speed connector. One speed monitoring pin transmits an output signal for monitoring the speed of the motor, and four speed setting pins receive input signals for setting the speed. One of the speed setting pins receives and decodes two binary states and two frequency states, thereby providing a total of thirty-two speed settings. A non-regulated isolated winding is added to an internal transformer to provide an internal isolated flyback power supply for the motor, thereby liberating a pin on the industry standard five pin speed connector to provide the fourth speed setting input pin. Transmission circuitry is associated with the speed monitoring pin, and the non-regulated isolated winding is used to provide a direct current bias to the transmission circuitry.
