Description
The motor is built in an aluminium housing with liquid cooling, protection degree IP6K9K. The electromagnetic design and the winding are matched to the traction inverter, so 3, 6 or 12 high-voltage terminals and several winding variants are provided for inverters from different manufacturers. The DC link voltage is 484–750 V in the LD version and 600–900 V in MD and HD, and the maximum rotational speed is 4500–4800 rpm. The series belongs to the ROAD segment, in which this manufacturer has worked since 2000. The motor can be obtained as part of a complete electric drive through partners. The design is developed, made and tested at the company's own test station in Austria, and an exchange pool, repair and modernisation are available for the whole service life. The products are made in Europe and may meet Buy America requirements.
How to choose
The size is chosen by peak and continuous (30 min) power. TMPW 25A-26-8 (Light Duty, LD.T3) gives 217 kW peak for 30 s and 94 kW continuously at torques of 1200 and 500 N·m; its weight is 125 kg, and the target vehicles have a gross weight of up to 9 t. TMPW 34A-28-8 (MD.T3) has 330/240 kW, 2500/1042 N·m and 275 kg. TMPW 40A-26-8 (HD.T3) delivers 420/350 kW, 4000/1519 N·m and 335 kg, and TMPW 40A-39-8 (HD.T3+) 550/470 kW, 5000/2500 N·m and 450 kg. If you need an induction motor, consider the TMF ROAD with a peak power of 240–427 kW. Data on driving cycles and the results of traction calculations are passed to the manufacturer to check energy consumption and winding temperatures.
