Industry
Defence ...
With its demand for equipment with extreme reliability and ruggedness, often for operation in confined spaces, the defence sector is a prime market for PMW’s compact motors
The company’s brushed printed armature DC motors are powering applications in military installations and vehicles, and are ideally suited for applications calling for low profile motors in environments where they may have to remain operational in temperatures of up to 150°C (302°F). These include motors for cooling fans, air movement fans, turret turning motors and positioning systems
Brushless motors from PMW are used in the manufacturing process of wheels and winches for bomb disposal robots, and for propulsion units for underwater use.
Challenger 2 Tank Ultra Slim Fan Motor Case Study
During the development PMW carried out extensive tests to ensure that all internal components were optimised for the specified conditions. The tests resulted in modifications to the bearing grease, brush materials and armature in order to withstand the temperature regime, plus additional RFI suppressing components to meet the rigorous electromagnetic compatibility (EMC) requirements
The motor achieved compliance with exacting military standards, with the DEFSTAN 00-35 British Ministry of Defence test regime requiring motors to be subjected to -20°C (-4°F) and +150°C (302°F) for two hours each. The motors then faced endurance tests of 750 hours of operation at 65°C (149°F) followed by 85°C (185°F), then by simulations of dust, sand and driving rain.
With its dual shaft seals, the printed armature motor also achieved an environmental IP55 rating
