Abstract
An electric motor is provided that is configured for operation in hazardous or other hazardous environments. The electric motor includes a housing for a rotor and a stator. The housing includes a pair of end caps and a casing positioned therebetween. The end caps and the casing are held together using internal tie bars extending between and connected to the end caps.
Claims20
An electric motor for use in hazardous environments, the electric motor comprising:
- a housing having a casing positioned between a head end cap and a tail end cap;
- an output shaft;
- a rotor attached relative to the output shaft and disposed within the housing;
- a stator at least partially surrounding the rotor and disposed within the housing;
- and
- a plurality of ties each extending between the head end cap and the tail end cap to hold the head end cap, tail end cap and casing together, the ties being positioned internally relative to the casing.
