Where This Motor Fits in a Low-Voltage E-Powertrain

As part of Shenzhen Jinhaixin Holdings’ low-voltage e-powertrain portfolio, this brushless hub motor is typically integrated with a drive controller and an energy battery pack. For OEM programs, we support component selection and customization across the system so that mechanical fit, electrical interfaces, and supply consistency can be aligned to your platform.

1) Brushless hub motor

Primary traction unit with fitment dimensions matched to small platforms.

2) Drive controller

Controls motor operation and supports integration requirements in low-voltage systems.

3) Energy battery pack

Provides system energy storage; pack customization can be aligned to application needs.

B2B Customization & Supply Support

Shenzhen Jinhaixin Holdings is a trade-and-manufacturing integrated enterprise with production bases across Shenzhen, Dongguan, Changzhou, and Hainan. For OEM and project customers, we can support customization discussions around fitment, system matching, and manufacturing coordination within our low-voltage e-powertrain scope.

Typical OEM inquiry checklist (to speed up evaluation)

Target application: kart / leisure vehicle / compact equipment
Required wheel size and space constraints (confirm 8", 200 mm diameter, 84 mm tire width fit)
Installation requirements and shaft structure preference (unilateral press-fit shaft)
Desired system scope: motor only vs. motor + controller + battery pack
Project stage: sample evaluation, pilot build, or production planning

Our approach is customer-centered and quality-driven: we aim to provide a clear product scope, stable quality management, and configurable low-voltage e-powertrain solutions without overstating performance outcomes.
