1. An electric motor comprising:
a) a stator having a stator slot; and
b) a composite material within the stator slot, the composite material including:
i) a matrix material; and
ii) additive particles having thermal conductivity, and anisotropic electric properties;
wherein the additive particles are oriented in an aligned configuration and set to provide the composite material with thermal conductivity and reduced electrical conductivity in at least one direction based on the aligned configuration.
