Technology: MOTOR AND DRIVES

Dynamic Boosting Systems Ltd designs and manufactures high-efficiency, brushless, DC motors and sensorless drives. The power range developed today is between 250 W and 2 kW, with nominal operating speeds ranging between 30,000 and 50,000 rpm. The efficiency is well above 90% (>95% electrical) for both motor and drive. This has been made possible by optimising the motor design and the careful selection of materials to reduce losses. The motors run on sealed-for-life, grease-lubricated ball-bearings of a type that is already in mass manufacture and which guarantee a long service life.
Many applications require a nominal operating voltage of 24V DC, but higher and lower voltages can be accommodated with different winding configurations. The company has just concluded a design for a high-power 12V automotive application, where design aspects for mass-manufacture have been considered.

The drive electronics are based on high-efficiency MOSFET designs and the selection of devices and microcontrollers are tailored the end application. The very latest, 8-bit micro-controllers with built-in memory help to provide low-cost solutions, whilst maintaining very high performance levels. DBS also has experience of designing the packaging and enclosures for operating in severe environments. Additionally, extra functionality, such as direct mass-flow control, can be accommodated for specific applications and control inputs/outputs can be either analogue or digital (PWM, CAN, RS232 etc).
