T-T Electric propses a series of three phase TAC-C ac motors in cast-iron frame sizes 80 up to 355 and from 0.18 up to 315 kW. TAC-C motors are designed and manufactured according to IEC34, IEC72, DIN42673, BS4999, AS1359, GB755, GB10069, and Q/JBQS27.

We hold on stock a large number of these references for immediate delivery to our customers. Our 10 and 12 pole range and any other special configurations have a 12 week delay.

Totally enclosed fan cooled IP55, our newly designed three phase TAC-C series of motors are suitable for all general purpose applications. Heavy duty design, manufactured from corrosion resistant cast iron materials to be used in all kinds of environments. The TAC-C series has the advantage of high efficiency and a powerful starting torque.

Technical features
High efficiency 1. 1 kW - 90 kW 2P and 4P, in S1 duty TAC-C motors are within the class 2 of CEMEP-EU standard, saving energy and operating costs. Voltage ranges A wide range of voltages up to a max. of 690 V available for 50 Hz and 60 Hz. Reliable windings To ensure long lifetime, the windings are made of the latest available materials in class F protection and temperature rise limited to class B in standard motors.	Strong corrosion protection The motors are made to withstand aggressive environments as standard and they are designed for long lifetime. For motors with regreasing possibility, they have strong and effective protection against corrosion. Bearings with high load capacity All motors are provided with long life heavy duty roller bearings. Cast iron motor in sizes 71-250 are greased for life and those in sizes 280-355 have regreasable bearings as standard.	Low noise level The TAC-C range has been designed to minimize motor noise levels by means of improving magnetic and electrical design, ventilator condition, structure size and technology. Winding protection PTC thermistors thermal-switches and anti-condensation heaters on request.
