–Brand New Design, IE4 efficiency
Rated Output
1TL8004 motors rated output powers means that the motor runs under continuous duty S1 (IEC 60034 – 1) operation when operated at ambient temperature from -15 ºC to 40 ºC and at altitudes of up to 1000 m over sea.
Voltage and Frequency
IEC 60034-1 differentiates between Category A (combination of voltage deviation ±5 % and frequency deviation ±2%) and Category B (combination of voltage deviation±10 % and frequency deviation +3 % / -5 %) for voltage and frequency fluctuations. The motors can supply their rated torque in both Category A and B. In Category A, the temperature rise is approximately 10K higher than during normal operation.
1TL8004 series motors are supplied with the ball bearing as standard. These bearings are re-greaseable type. For FS80 ~ 90, the floating bearings are assembled. For FS315 ~ 355, floating bearing at DE, and fixed bearing at NDE assembled. The standard bearing can endure a maximum cantilever force, the increased cantilever bearing design (Option code: L22) should be considered.
1TL8004 rotors are dynamically balanced to severity grade A using a half key. Table below contains the effective vibration values for unloaded motors.
Motors can be equipped with anti-condensation heaters (Option code: Q04). Anti-condensation heaters must be switched off during operation. When motor shut down, the heaters must be switched on.
