Traction motor

ISG (Integrated Starter Motor and Generator)

The main role of ISG is starting the vehicle's engine as well as charging the battery of hybrid

vehicle. ISG is specially designed for the hybrid vehicle. A hybrid vehicle can cut fuel consumption

and emission. S&T Motiv has proved ISG technology by producing various sizes of ISG.

Traction motors are to electric vehicles as engines are to gasoline vehicles. It features high peak

torque and strong power as the heart of electric vehicles. S&T Motiv produces wide range of

motors installed in hybrid and electric vehicles such as all-electric compact vehicle, fuel cell

electric vehicle and CNG Hybrid-Electric Bus.

EPS uses an electric motor to assist the driver of a vehicle. Changing engine power to motor power

reduces fuel consumptions and makes the stable performance. Recently, controlling EPS can be applied

from the automatic parking to self-driving car. S&T Motiv is making a variety forms of EPS that attach

from the axle to the steering wheel.

Transfer case actuator is the power distribution system of the

vehicles. The power is distributed by transfer case actuator to the

front and rear wheels depending on the driving conditions. Allowing

freely adjustable in two-wheel drive to four-wheel drive, it helps

the vehicle can run in various environments

DCT (Double-Clutch Transmission) actuator

Transfer case actuator

A DCT actuator moves double-clutch rapidly, which makes gear shifting quick and smooth. It reduces a fuel

consumption and enhances a driving performance. S&T Motiv's DCT actuator has been adapted for next

generation transmission such as 6speed-DCT and 7speed-DCT.

eMotors and Pumps supply oil to the transmission. The electronic motor is the main power supplier for the oil

pump. Not only does it increase engine efficiency but also controls the amount of transmission oil. It has been

continuously selected in hybrid vehicles, as well as next-generation powertrain.

Azimuth Drive is the large motor mounted in Chon-goong(Cheolmae-II) that is one

of the Korea National Defense Weapon System. It enables the multifunctional radar

to rotate in all directions. S&T Motiv has been introducing the motor manufacturing

technology that can precisely control the large object weighing more than 2 tons.
