DMC (Digital Motor Control) GmbH, is a company with a dedicated team of individuals with many years experience in the design, manufacture, sales and after market support of controllers predominately utilised in the electric vehicle industry. DMC has invested in a purpose built state of the art production facility. The Company has been formed with enthusiasm and professionalism to create and develop a unique new product range in this particular "niche" industry where specialist knowledge and experience are essential for success.
Utilising revolutionary power heat sinking technology called IMS (Insulated Metal Substrate) a new generation of highly efficient controllers for all popular motor types can now be offered from a single core design, in the 24V - 120V, 1KW - 24KW power range. Using 'flash memory' in the control electronics coupled with a unique design architecture, all powers and motor types including AC, PMS, Separately Excited, Permanent Magnet and Series, can be accommodated within 3 standard power frames. Particular attention has been placed on providing high-resolution control circuitry and software, to provide fully optimised, highly efficient motor control.
The principle advantage of IMS technology (which can be visualised as a metal PCB) is that cost effective SMD Mosfet power devices can be mounted and soldered directly onto the IMS PCB, which provides immediate and excellent 'integral' heat sinking. Consequently, reliability and efficiency are significantly enhanced due to the power switching devices running cooler and therefore inherently more efficiently. This approach also leads to significantly improved continuous power delivery (1 hour current rating), as a ratio to peak power, with the controllers continuous rating normally being one of the most important aspects in determining the vehicles performance.
By using an innovative technique, DMC has fully exploited IMS technology to realise a unique controller design. The construction provides manufacturing simplicity and reliability by removing the need for any interconnections and using a minimal number of mechanical and electronic components. This gives a totally robust and environmentally sealed, space efficient controller .
An additional feature, a ground breaking concept which epitomises DMC 's innovative spirit, is the Directly Integrated Current Control module. This module is at the heart of all DMC controllers and provides continuous, real time control, of motor power delivery, whilst at the same time providing full, instantaneous hardware protection, against any over current fault condition.
A full range of associated accessories and support infrastructure completes the DMC service.
To conclude, in our specialised purpose built facility, a fusion of creative thinking, collective experience and latest state of the art technology, has produced what we believe to be the most flexible and thermally advanced controller range available in the market place to date.
