Abstract: A system for determining operating conditions of a rotating biological contactor includes a sensor including a first end coupleable to the gearbox assembly of the rotating biological contactor at a radial distance from a rotation axis of a rotatable shaft. The rotatable shaft rotates a plurality of media elements about the rotation axis to treat water within a basin of the rotating biological contactor. The sensor also includes a second end coupleable to a brace to prevent rotation of the sensor and the gearbox assembly when the rotatable shaft is rotated. The sensor further includes a body extending between the first end and the second end. The sensor is configured to detect a load on the body when the rotatable shaft is rotated. The system further includes a controller communicatively coupled to the sensor. The controller is configured to determine a torque of the rotatable shaft based on the load detected by the sensor.

Abstract: A lamination for use in an electric machine stator includes a body having a generally circular outer periphery and a generally circular inner periphery, spaced from the outer periphery and a plurality of spaced apart teeth extending inwardly from the circular inner periphery. Each of said teeth define opposed inner edges thereof. The lamination includes a first pair of tips extending tangentially in opposed directions from the inner edge of one of said teeth and a second pair of tips extending tangentially in opposed directions from the inner edges of another one of said teeth. A tip of the first pair of tips and a tip of the second pair of tips define a first configuration having a first gap therebetween and defining a second configuration having a second gap therebetween. The first gap being substantially less than the second gap.

Abstract: A motor controller and methods for operating a motor are described herein. The motor controller includes a high-frequency (HF) inverter having a direct current (DC) input stage and an alternating current (AC) output stage, the HF inverter operable at a switching frequency to generate a three-phase output having a fundamental frequency. The motor controller also includes a differential mode (DM) filter coupled in series with the output stage of the HF inverter and having a resonant frequency less than 10% of the switching frequency, the DM filter configured to reduce harmonic components of the three-phase output and generate a first filtered output. The motor controller further includes a common mode (CM) filter coupled in series with the DM filter, the CM filter configured to filter the first filtered output to generate a second filtered output having a reduced CM voltage to operate the electric motor with a reduced bearing current.
