3 M-II Series Motor Enclosures Output: 0 Hz 0 ~,00 KW (0~,0 HP) 0 Hz 00 ~,0 KW (0~,0 HP) Voltages:,00 V ~,000 V Insulation Class: F Class Standards: IEC, NEMA, BS, AS and others available Totally-Enclosed Air-Water- Cooled Type TEWAC/IP This type of motor is especially useful in a location where low noise operation is required or where it is desired to remove heat from the area where the motor is located. The motor includes an air-to-water heat exchanger in the air housing above the motor. A drain in the air housing protects the motor from damage should any water leakage ever occur. Totally-Enclosed Air-Air Cooled Type TEAAC/IP In an environment containing corrosive or harmful gas, a totally- enclosed fan-cooled motor can be applied. An external fan mounted on the opposite drive end shaft directs fresh air through the pipes in the air housing above the motor. The pipes serve as a heat exchanger in which outside fresh air passing through cools the hot air inside. NEMA Weather-Protected WPII/IP This motor is designed for outdoor operation. In accordance with NEMA WPII, the housing air path includes right-angled turns, dropping air intake air velocity below m/sec (00 ft/min.). This traps water, dust, and foreign materials. A section is provided that allows air to pass through without being forced into the motor. Open Drip Proof Type ODP/IP A drip-proof type motor is a common choice for a protected, well-ventilated room. Cooling air intake and hot air exhaust windows are located at the top of the hood. Openings are covered by screens and enclosure is constructed to prevent intrusion of water drips and other foreign materials into the motor meeting NEMA WP-I requirements. Common Foundation Base IC0, IC and ICW cooling per IEC Standard construction are available by changing the top-mounted air housing. The main terminal box can be rotated through 0 angles, and is large enough for easy cable connection. A shaft current protection insulator in the non-drive end bearing on 0 frame and larger, and all sleeve bearing machines, is included as standard.

4 Features of MII Series Motors Reliability & Easy Operation/Maintenance Main Terminal Box Box NEMA Type II terminal box is standard. Boxes including surge protection and/or differential CT's are readily available. Standard main terminal box can be rotated every 0. Adequate space is allowed below main terminal box for cable connection. Stator Core core Stators are high-grade electrical steel with low magnetic losses. Stator core winding is pressed into the center of the frame and locked against rotation and axial displacement. Frame Fabricated steel construction increases the ridigity of the stator frame. Low vibration is achieved through frequency analysis. Auxiliary Terminal terminal Box box When applied, the modular arrangement for accessory connections allows flexibility with standardized mechanical construction.

5 Air Housing NEMA Open Drip Proof (IP) construction provides protection from dripping liquids and foreign materials. NEMA WPII (IP) top hood construction prevents instrusion of rain water and foreign matter. IP protection is standard on TEAAC (aircooled) and TEWAC (water-cooled) motors, and isolates the motor interior from environmental contamination. Stator Coil Utilizes a highly reliable, vacuum pressurized impregnation (VPI) insulation system providing firmly-fixed coil ends with the ability to withstand most environments. Bracing ensures long life despite the stresses imposed by starting and duty cycles. Rotor Aluminum die cast rotor is standard; copper rotor bars are available as an option. Aluminum rotor construction results in high capacity, high reliability, better frequent starting duty and lower inertia. Bearing Antifriction and sleeve bearings are easily maintainable. Antifriction (ball, roller) bearings use a refined lubrication design that makes regreasing simple.
