 Recognising the importance of the Australian EV market, we now have a new exclusive distributor.
This is EV Works PTY (http://www.evworks.com.au) which has long worked in the field and has achieved a premier status as EV parts supplier in Australia.
The first shipment is expected to hit Australian shores in May. |

| 2010 SEES THE KOSTOV 13" WITH AN UPGRADE. |
| 13 Jan 2010 |
The latest motor to benefit from an improved collector is the 13" 144V.
It successfully passed tests at up to 220V/315A becoming the most powerfull single motor in our range at 57kW.
Torque is double that of the 11" standing at 140Nm. |

| NEW 11" COLLECTOR |
| 17 Dec 2009 |
 The collector used for all 11" models has been further improved.
The classical dove-tail lamella construction has been changed to allow higher rpm while the plastic material has been upgraded too. Also featured are two metal rings to help keep the lamellas together.
This has resulted in a collector that is superior in terms of mechanical strength and temperature endurance. |

| KOSTOV 11" 250V IS NOW AVAILABLE FOR ORDERING |
| 14 Oct 2009 |
This new product brings EV motors to a whole new level.
It is the first in our Kostov portfolio to use series/parallel switching of the field windings (see FAQ section).
The switching makes it the most versatile motor ever allowing it to cover the 144-250V range at optimal rpm despite voltage.
It is the perfect companion to Zilla1K HV with recommended battery pack voltage of 288V to take account of voltage sag.
We are currently researching the possibility to use Zilla's autoshift function (option A) to switch between modes. |

| ZILLA CONTROLLERS |
| 08 Oct 2009 |
 As part of our efforts to offer high quality components, we have reached a dealership agreement with Electric Vehicle Components LLC (www.evcomponents.com) to start selling Zilla controllers. The website will soon be updated with prices for these as well as for motor+controller kits. |

| TESTS OF THE DUAL KOSTOV 11" MOTOR HAVE FINALLY FINISHED |
| 15 Aug 2009 |
 The most powerfull direct current motor for EV conversions is now available.
It will be sold under the name of Kostov 11" 400V and consists of two 11" 192V motors joined together via male/female splines in the shafts.
When connected in series, it can handle 250A at 400V giving over 80kW.
Alternatively, when used in parallel it can take 500A at 192V achieving again 80kW at this lower voltage.
The Kostov line of motors section on our web site will soon be updated to include pricing, drawings and characteristics of this motor. |

Another 11" motor is added to the range.
It is rated at 144V nominal (5350rpm) and allows 3500rpm at 90V.
It is aimed at the "mass" market for EV motors concentrated at 96-144V.
It has by far the highest amp handling amongst the 11" group - 280A. |
