Techtop’s TCI/TCP cast iron series motors combine superior electrical characteristics, high quality design and the robust strength of cast iron, making this series ideal for all industrial applications.

Operating parameters

Standard TCI/TCP series motors are designed with the following parameters:

• 380V to 415V, 50Hz & 440V to 480V, 60Hz supply

• Continuous (S1) duty

• Ambient temperatures up to 40°∆C

• Installation up to 1000 MASL

• Connection

• 230V Delta / 400V Star (3kW & below)

• 400V Delta / 690V Star (4kW & above)

Standards

Dimensions and rated outputs for the TCI/TCP series conform to Australian Standard AS/NZS 1359 and International Standards IEC 60034 and IEC 60072.

Standard & High Efficiency

The TCI range complies with MEPS2 requirements of AS/NZS 1359.5:2004 Table A2 (Standard Efficiency). The TCP range complies with MEPS2 requirements of AS/NZS 1359.5:2004 Table A3 (High Efficiency). Motors are tested in accordance with Test Method A of AS/NZS 1359.102.3 as per IEC 60034-2-1.

Insulation class

TCI/TCP motors are insulated with Class F materials and limited to Class B temperature rise. The windings are spike resistant making them suitable for use with VVVF drives.

Thermistors

As standard all TCI/TCP series motors from 160 frame and above are fitted with one set of PTC thermistors. The thermistor termination is located in the main terminal box and has a trip temperature of 150°∆C as standard. Additional 130°∆C thermistors can be fitted as an option for alarm connection. Thermistors are available as an option for smaller frame sizes.

IP Protection

The standard degree of enclosure protection is IP 55 (increased IP protection is available). Shafts are fitted with an oil seal as standard.

Multi-mount design

TCI/TCP series motors from frame size 80 to 280 are fitted with detachable feet. The multi-mount design allows for the motor feet to be removed and repositioned to either side to produce a side mounted terminal box.

Terminal box

The terminal box is manufactured from cast iron and is mounted on top of the motor as standard. Terminal box is separate to the motor body and can be rotated in 90°∆ increments.

Surface Finish

As standard TCI/TCP motors are painted with high quality alkyd enamel with the final colour being RAL 9005 Jet Black. Other colours are available upon request.

Bearings

Bearings fitted are high quality NSK bearings with C3 diametrical clearances. As standard, frame sizes 80 to 132 have sealed for life deep groove ball bearings. Frame sizes 160 to 355 have re-greaseable bearings with facilities to replenish the grease during operation. Grease nipples are fitted to the top of the end shields with a grease relief fitted at the bottom.
