The invention provides an electric machine for a hybrid/electric vehicle. A vehicle includes a battery, an electric machine, a thermistor, and a controller. The electric machine is configured to draw power from the battery to propel the vehicle. The electric machine has a rotor and a stator. The stator has a core, an interconnection hairpin, and a neutral bus bar. The core defines a slot. The interconnected hairpin windings are arranged within the slots and are arranged to form a plurality of electrical phases. The neutral bus is connected to each of the electrical phases and defines an aperture. The thermistor is disposed within the aperture and is configured to sense a temperature of the motor. The controller is programmed to control a power output of the electric machine based on the temperature of the electric machine.
