What is an integrated motor drive (IMD)?
The term ‘integrated motor drive (IMD)’ is the latest associated with this class of products and is as a result of the success of a TB Woods Inc. manufactured motor-drive registered under the same name . IMDs are increasingly being developed and produced by machine manufacturers due to the significant potential benefits they offer.
What is a commercial high power modular IMD?
Commercial high power modular IMDs with ratings up to 16.5 MW are currently manufactured by Siemens under the integrated drive systems range . This is a variation of the surface (radial) mount configuration with converter mounting position dependent on available space in the axial direction.
What is the power rating of an IMD?
Both IMDs are for electric vehicle applications with high power ratings of 250 and 45 kW, respectively. Other manufacturers include TB Woods and ABB with a mid-range power rating portfolio between 3.7 to 7.5 kW [35, 36]. Typical applications include EV where surface integration is difficult due to lack of space in the radial direction.
Are modular drives a good choice for IMD design?
Improved thermal capability is another possible advantage. This is as a result of having individual lower rated components and more evenly distributed heat dissipation . Due to these potential benefits, modular drives are very beneficial for IMD design.
What is an IMD & how does it work?
For the purpose of this work – an IMD is the result of the functional and structural integration of the power electronics (PE) converter with the machine as a single unit taking into consideration the electrical and structural and thermal impacts both components have on each other and the system as a whole.
What is IMD design?
IMD design should involve a holistic analysis of the thermal, mechanical and electrical effects of the IMD components and the cooling system as a single unit. Manufacture of more mid and high power rated IMDs is expected with advancements in material and packaging techniques.
