Installation &Commissioning

TMEIC products are insulated using strict procedures and materials of the highest quality; features that contribute to stable, nonstop operation and a long service life. Advanced production, delivery and installa-tion knowledge greatly shorten the start-up time for commissioning a system, minimiz-ing the risk of delays, improving productivity and promoting trouble-free operation.

TMEIC supplies motors and generators glob-ally using some of the most advanced pro-cesses in the industry. The service network ensures efficient installation and commis-sioning of products, bringing direct benefits to customers by minimizing start-up time, and the risk of downtime and lost productivity. Sophisticated verification is utilized for onsite measurements when conducting machinery replacement.

Superior Insulation Long Service LifeTMEIC motors and generators feature insulation quality second to none,

a key factor for ensuring a long and reliable service life.Eliminating the need to frequently update or repair equipment helps

to reduce costs and enables smoother, more efficient operations; features that contribute to maintaining the highest level of productivity.

Totally Enclosed Fan CoolingSystemClassifications: IC411, IP55TMEIC motors equipped with totally enclosed fan cool-ing systems are designed to comply with IC411 and IP55 classifications. The fan is mounted on the rotor and en-closed in the case so that the cooling-air flow is directed over the surface of the motor. Enclosure with IP55classification are designed to prevent dust infiltration, thereby prohibiting particulates from reaching the motor and ensuring smooth, continuous operation. They are also designed so that water sprayed onto the framefrom any direction is prevented from permeating and causing any harmful effect. Applicable frame sizes: 250SA-280MD, 280L, 315H-630.

Weather-protected Type II CoolingSystemClassifications: IC01, IP24WTMEIC motors equipped with weather-protected type II (WP II ) cooling systems are classified as IP24 and IC01 under IEC standards. The ventilation passages in these motors are protected so that rain, snow and air-borne particles cannot permeate electrical components. Both the intake and exhaust ventilation passages are de-signed with at least three 90-degree elbows in thedirection of airflow, and the airflow speed in the low-velocity area in the intake-air path does not exceed 600ft/min.

Totally Enclosed Air-to-air CoolingSystemClassifications: IC611, IP55TMEIC motors equipped with totally enclosed air-to-air cooling systems are classified as IC611 and IP55 under IEC standards. These motors are cooled through a heat-exchanging process that utilizes internal air circu-lated through the heat exchanger. Both air re-circulated through the motor and external air drawn in are circu-lated by the fan mounted on the motor shaft and driven by the rotor. The minimum applicable frame size is 315-1000, and the standard cooling tube material is either corrosion-resistant treated carbon steel or stainless steel. Machines in the IP55 classification are designed to prevent the permeation of dust that could interfere with proper operation of the machinery. They are also built so that water sprayed onto the motor from any direction has no harmful effect.
