TENV

Totally Enclosed, Non-Ventilated – A standard cooling option available on Pharmaceutical, Marine, and Food Processing Motors up to 1 HP. For these motors, all heat is dissipated through the motor housing and endbells. Surface temperatures are higher than comparable TEFC motors, but cleanability is enhanced.

TEFC

Totally Enclosed, Fan Cooled – The most popular standard option. A fan attached to the rear end of the motor shaft blows cooling air over the body of the motor. Available on all motors between ¼ and 30 HP.  Note that air flow is dependent on shaft speed.

TEBC

Totally Enclosed, Blower Cooled - A separate blower motor attached to the motor provides a constant flow of cooling air over the motor at all speeds. This cooling option is suggested for all inverter-driven motors with turndown ratios to 10:1.  As the blower motor requires its own source of power, separate wiring is included  and  brought out through the main motor junction box.

TECAC

Totally Enclosed, Compressed Air Cooled - Compressed air is passed through the motor at low pressure. Stainless Motors^TM, Inc. will provide suggested air flow values for each specific application.  This option affords a TENV-type enclosure with no external fan, for ultra sanitary environments or areas which cannot tolerate the air flow from a fan.

TEFCAC

Totally Enclosed, Fan Cooled, Compressed Air Cooled - This option is similar to the TEFC motor, however, compressed air ports are provided so that additional cooling may be provided during extreme operation. Typically found on inverter driven motors which must provide full torque below the standard 4:1 turndown.

TELC

Totally Enclosed, Liquid Cooled - By far the most efficient cooling means. Cooling liquid, typically water, is circulated through a special cooling jacket built into the motor.  Applications include high power/small frame requirements, absence of cooling air (vacuum), or high power without the air disruption of an external cooling fan.  A remote radiator or heat exchanger is required.

TEOT

Totally Enclosed, Oil Through - High dielectric oil is circulated through the motor winding.  Relatively rare, applications include partial or full submersion in extremely hostile environments.
