24 Nov 16. Traditional winch motors superseded by PMW design. Winches mounted on military and other vehicles have traditionally used brushed motors that are heavy and inefficient, and typically unable to operate continuously for more than a few minutes before overheating. Tasked with addressing this issue, Printed Motor Works has developed a new motor which, paired with a suitable electronic controller, will be able to deliver vastly improved performance. The brushless motor has a much greater efficiency and so produces less heat, enabling a much better duty cycle. The motor and controller will be considerably smaller and about half the weight of traditional winch motors, which can be a crucial factor in heavily equipped vehicles.
“The winch market is currently supplied by manufacturers using very basic brushed motor technology that is not fit for purpose,” said Ian Matthews Golledge, project engineer at Printed Motor Works. “That is why our use of the latest technology makes such a big improvement.”
The motor is also suitable for larger winch systems, as it has lower installation costs and lower overall power consumption than hydraulic systems, as well as taking up much less space.
Winch motors for military vehicles require an immense torque for short durations in the smallest and lightest possible package, and the PMW design meets precisely these requirements. A further advantage is that the motor produces dramatically less electromagnetic interference, greatly reducing its EMI signature and making it less likely to interfere with neighbouring systems. As well as in light tactical vehicles, the motor and controller package has great advantages for use in commercial recovery vehicles and for shipborne winches on fishing vessels for example.
24 Nov 16. Carmel FCV set to feature two-man crew system, emerging technologies. Further details of Israel’s Carmel Future Combat Vehicle (FCV) programme have been revealed by the head of the team leading the Israel Ministry of Defence (MoD) development programme. Speaking at the SMi Future Armoured Vehicle Survivability conference in London, Brigadier General (rtd) Didi Ben Yoash stated that three companies – Elbit Systems, Israel Aerospace Industries, and Rafael Advanced Defense Systems – are to develop a two-man crew system for the FCV by 2019 through a feasibility study. A winner will be selected to equip the FCV vehicle following trials. Emerging technologies are to be integrated into the vehicle’s design from the outset, with the research and development programme intended to form the basis of an entire family of future Israel Defense Forces (IDF) vehicles.

22 Nov 16. Industry proposals on how to meet a requirement for a key armored vehicle for the British Army dropped on the desks of Ministry of Defence (MoD) procurement officials Tuesday, even as claim and counter-claim continue to reverberate around the sector on whether the government will hold a competition or hand the deal to German supplier ARTEC.
Responses to what is known as a preliminary market engagement questionnaire released by the MoD were lodged Nov. 22 ahead of a decision — to take place in the second quarter of next year — on an acquisition strategy for a mechanised infantry vehicle (MIV) program. The program likely will involve the purchase of more than 500 armored personnel carriers and other variants.
The questionnaire is meant to start answering queries about the capabilities of off-the-shelf in-service vehicles, possible local industry content and other issues. Yet some industry executives here claim it has as much to do with bolstering the case for a government-to-government (G2G) deal to buy ARTEC’s eight-wheel drive Boxer vehicle as anything else and are trying to derail any single-source deal. ARTEC is a jo
