Abstract: An induction motor cooling system is disclosed. The induction motor cooling system comprises a plurality of interconnected cooling channels and a plurality of air ducts characterized between inner circumference and outer circumference of the stator frame. The plurality of interconnected cooling channels is designed in a pre-designed meandering fashion to envelop the stator frame. And similarly, each of the plurality of air ducts of pre-defined dimension is axially positioned in equidistance spread to envelop the stator frame. Cooling channels enable flow of coolant liquid to dissipate heat produced by the stator coils. Air ducts helps in cooling the stator coil temperature and the rotor temperature by inflow and outflow of air. Air entry and exit to the plurality of air ducts is enabled by a set of inflow air openings and a set of outflow air openings fabricated on the inner circumference of the stator frame.

Abstract: An induction motor is disclosed. The induction motor comprises a motor casing, fabricated in an irregular octagonal shape with a central open area. The motor casing is configured to house a cooling system within an outer wall and an inner wall of the motor casing.

Abstract: Embodiments relate generally to systems and methods for determining the location of a gas detector device, wherein the location may be within a predefined location zone, and automatically configuring the gas detector device based on the location zone. Each location zone in a facility may be associated with a configuration for the gas detector device. The location of the gas detector device may be monitored by a central station, and when it is determined that a gas detector device has moved from one location zone to another, the configuration of the gas detector device may be updated accordingly. Additionally, other parameters may be monitored by the central station and/or the gas detector device to determine the appropriate configuration of the gas detector device.
