Kostov Motors at Hannover Messe 2017

Kostov Motors took part again in Hannover Messe in Hall 21 within the Motion, Drive and Automation expo. The venue is a great opportunity to meet old clients, find new ones and discover the developments in our market segment as well as share on the latest gossip :)

A 3-phase 48vac motor is the latest addition to the Kostov line

Our first Ac motor that is good for electric vehicles is a fact.
Starting with 5.5kW at 48V, it is meant for the smallest vehicles and has the form factor of the classical K9" motors.
A major distinction is its IP44 rating making it completely enclosed.
Also in the plans is a 96V version that will hit the market in the next 2-3 months.

2010 sees the Kostov 13 with an upgrade
The latest motor to benefit from an improved collector is the 13" 144V.
It successfully passed tests at up to 250V/315A becoming the most powerfull single motor in our range at 65kW.
Torque is double that of the 11" standing at 140Nm.
NEW 11" COLLECTOR

NEW 11 COLLECTOR
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
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.

TESTS OF THE DUAL KOSTOV 11 MOTOR HAVE FINALLY FINISHED
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. TRACTION MOTORS MARINE APPLICATION MOTORS KOSTOV MOTORS, AC MOTORS, DC MOTORS

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.
