- Company Profile:
An inherent overheating protective device which is responsive to motor temperature and which, when properly applied to a motor, protects the motor against dangerous overheating due to overload or failure to start. This protection is available with either manual or automatic reset.
Industry:Electrical equipment
A semiconductor used to measure temperature; can be attached to an alarm or metre to detect motor overheating.
Industry:Electrical equipment
A temperature detecting device made of two dissimilar metals which generate a voltage as a function of temperature. Thermocouples can be attached to a metre or alarm to detect overheating of motor windings or bearings.
Industry:Electrical equipment
Units applied directly to the motor's windings which senses winding temperature and may automatically break the circuit in an overheating situation.
Industry:Electrical equipment
Turning force delivered by a motor or gearmotor shaft, usually expressed in lbs. ft derived by completing H.P. x 5250/RPM = full load torque.
Industry:Electrical equipment
A motor enclosure which prevents free exchange of air between the inside and the outside of the enclosure but is not airtight. Different methods of cooling can be used with this enclosure.
Industry:Electrical equipment
A totally enclosed machine cooled by circulating internal air through a heat exchanger which, in turn, is cooled by circulating external air. Provided with an air-to-air heat exchanger for cooling ventilating air and fan or fans integral with rotor shaft or separate, for circulating external air.
Industry:Electrical equipment
Provides for exterior cooling by means of a fan(s) integral with the machine, but external to the enclosed parts.
Industry:Electrical equipment
Has no provisions for external cooling to the enclosing parts. The motor is cooled by heat radiation from the exterior surfaces to the surrounding atmosphere.
Industry:Electrical equipment
A totally-enclosed machine except for openings so arranged that inlet and outlet ducts or pipes may be connected to them for the admission and discharge of ventilating air. Air may be circulated by means integral with the machine or by means external to and not a part of the machine. In latter case, these machines shall be known as separately-forced-ventilated machines.
