Every Parameter, Developed for Your Application
Every power tool and battery-powered application has different motor requirements. The 3820 is not restricted to one fixed electrical or mechanical configuration — Dongke can develop the motor according to the customer's specific requirements.
Voltage
Motor voltage can be developed according to the customer's battery and power system.
Speed
The required motor speed can be configured according to the operating requirements of the equipment.
Torque
Motor torque can be developed according to the required load, working conditions and application.
Power
The motor output can be configured according to the equipment's required performance.
Motor Dimensions
Motor dimensions can be developed to suit the available installation space and equipment structure.
Shaft & Mounting
Shaft dimensions, mounting structure, wiring and connector can be customized according to the customer's system design.
From Requirement to Production
Dongke provides OEM and ODM motor solutions for customers who require application-specific brushless motors. The development approach allows customers to obtain a motor designed around their equipment instead of adapting a standard motor to an unsuitable application.
OEM Brushless Motor
For customers with defined motor specifications, drawings, samples or technical requirements, Dongke can manufacture the motor according to the agreed requirements.
ODM Brushless Motor
For customers who have an application but require assistance developing a suitable motor solution, Dongke can work from the equipment requirements and application conditions to develop an appropriate motor configuration.

Why Choose a Custom 3820 Motor?
Dongke develops and manufactures brushless motor solutions for OEM and ODM applications. Our motor solutions are designed for customers who require application-specific electrical and mechanical characteristics.
Application-Specific Design
Instead of adapting an off-the-shelf motor to the equipment, the motor can be developed around the actual application requirements.
Flexible Configuration
Electrical and mechanical characteristics can be developed according to the customer's requirements.
Complete Drive Solution
The motor can be matched with a suitable brushless controller for a coordinated drive system.
Designed for Mass Production
After the motor configuration is confirmed and samples are approved, the solution can move into production according to agreed manufacturing requirements.
Built for Global OEM Standards
Dongke Electric products are manufactured in our ISO 9001:2015 facility with UL- and TUV-certified in-house laboratories. Every unit passes four quality gates before it ships.
Four Quality Gates, One Reliable Product
Each stage is backed by documented procedures, trained personnel and calibrated instruments.
IQC
Raw materials and components are inspected on arrival. We verify material certifications, dimensional accuracy and electrical properties against our specifications.
IPQC
Automated assembly lines are checked at every station. Regular line inspections, first-article checks and SPC monitoring detect and correct deviations in real time.
FQC
Every unit is tested before shipment. Key parameters including contact resistance, insulation resistance and switching operation are verified on 100% of products.
OQC
Packed batches are re-checked before dispatch. Our team performs sampling inspections based on AQL standards, verifying packaging integrity and labeling accuracy.
Dongke Electric operates a dual-accredited testing laboratory (UL + TUV) — a distinction shared by only a handful of manufacturers in our industry.
Frequently Asked Questions
Dongke provides a complete ecosystem of core components for cordless power tools — from battery holder connection to custom motor power output — enabling OEM customers to source an integrated solution from a single manufacturer. (Battery is excluded)
