As the external static pressure increases, the amp draw of a Permanent Split Capacitor (PSC) motor will increase. This is attributable to the motor working harder to overcome the additional resistance created by the increased static pressure. In essence, the increased load on the motor results in greater torque demands, which in turn requires more electrical current to maintain the motor’s performance. In a PSC motor, this relationship between load and power consumption is particularly evident because the motor's design allows it to draw a higher current to generate more torque when faced with increased resistance. As static pressure rises, the motor is required to exert additional energy, reflected in a higher amp draw to sustain operational efficiency. This is a fundamental characteristic of electric motors, where as the demand increases, so does the current draw, ensuring that the motor can perform its intended task despite changing external conditions.
