Techtop Motor 4kW 2P 415V B5 TAI 112M-2

Techtop’s TAI aluminium series motors are suitable for all industrial applications where optimal design performance and low weight are key factors.

Standards

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

Efficiency

The TAI range of motors complies with MEPS2 requirements of AS/NZS 1359.5:2004 with many ratings meeting High Efficiency levels of the same standard. TAI motors also meet European IE2 (High Efficiency) levels as set down in IEC 60034-30 international standards. Motors are tested in accordance with Test Method A of AS/NZS 1359.102.3 as per IEC 60034-2-1.

Insulation class

TAI 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 TAI 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 1500C as standard. Additional 1300C 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 on flange mount and a V ring seal on foot mount.

Multi-mount design

As standard, TAI series motors 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. Alternatively the feet can be removed and the motor mounted from any of the 16 mounting pads.

Fan & Gearbox application

TAI series motors are low weight design and come standard with a drilled and tapped hole in the shaft which makes this series ideal for fan applications. This motor series is also ideally suited for fitting to aluminium gearboxes. *Optional B5R flange is available for gearbox fitment – B5R flanges are one frame size smaller than standard B5 flanges.

Terminal box

The terminal box is manufactured from aluminium and is mounted on top of the motor as standard. Terminal box is separate to the motor body and can be rotated in 900 increments.

Surface Finish

As standard TAI motors are painted with high quality alkyd enamel with the final colour being RAL 7024 Graphite Grey. Other colours are available upon request.

Bearings

Bearings fitted are high quality NSK deep groove ball bearings that are sealed for life.
