Do you keep stock of brushless DC motors?

Yes. Popular frame sizes from 42mm to 110mm in 24V and 48V variants are held as stock, with typical shipment within 5 to 7 working days from order confirmation. Custom voltage, shaft or gearbox variants build to order in 3-4 weeks.

Can Shenghe be our long-term BLDC motor supplier?

Yes. Most of our buyers are OEMs and system integrators placing recurring orders for the same motor families. We assign a single engineer to the account so technical questions do not bounce between sales reps, and we hold spares of the active models to protect your production schedule.

Do you supply matched controllers too?

Yes. BLD-series 6-step controllers and BLDB-series FOC controllers are validated as a pair with the motor and ship together. This prevents phase-to-Hall mismatch problems that are common when motor and controller come from different vendors.

What happens if a motor fails in the field?

Shenghe operates a replacement service for running production lines. Contact us with the serial number and failure description; for common frame sizes we can ship a replacement from stock within the same week. Warranty claims are handled on the test report tied to the original shipment.

Can I consolidate motors, gearboxes and controllers under one supplier?

Yes. That is the main reason OEM buyers choose us over single-product suppliers. Motors, planetary or worm gearboxes, controllers, cables and connectors all come from Shenghe, shipped together and invoiced on one purchase order.

Brushless DC Motor Supplier

A Stable BLDC Supplier For OEM Production Schedules.

Shenghe works with OEM buyers and system integrators who need a reliable brushless DC motor partner, not a one-time vendor. Popular frames stay on the shelf, matched controllers ship in the same carton, and the same engineer handles your account from sample to recurring order.

Attention

What OEM Buyers Need From A BLDC Supplier

A good supplier keeps your production line running. Buyers tell us the same pain list every week: inconsistent lead time, slow engineering answers, missing spares when a motor fails in the field, and separate invoices for motor, gearbox and controller from different vendors. We designed our supplier model around removing those frictions.

Lead time that holds steady order after order
Engineer who actually answers sizing and Hall wiring questions
Same-week replacement when a running line loses a motor
One purchase order for motor + gearbox + controller
Traceable test record tied to each serial number

Desire

Why OEMs Stay With Us

No mid-project supplier hunt: Stock on popular frames means you are not chasing a replacement when a line goes down at 2 AM.
One engineering contact: Technical questions do not rotate through three sales reps before reaching the factory.
Motor + gearbox + controller on one PO: Eliminates the usual 3-vendor, 3-lead-time, 3-warranty coordination headache.
Validated pair shipment: Motor and controller are tested together before leaving, so commissioning does not discover a phase-to-Hall mismatch.
Traceable QA: Every motor has a test sheet you can match to the serial at failure analysis time.
Lead time you can plan around: 5-7 days stock, 3-4 weeks standard production, honored on repeat orders.

How The Supplier Relationship Works

Sample phase

Send your technical sheet. We quote, ship a sample from stock in 5-7 days, and answer integration questions through the same engineer who will handle production.

Production onboarding

On first production order we lock voltage, shaft, Hall wiring and controller pair into a build spec document so every repeat order builds the same part.

Recurring supply

Repeat POs ship within the agreed lead time against the locked spec. Monthly forecast welcome but not required — we hold stock on popular frames.

Field support

If a motor fails, contact us with the serial number. We pull the original test record, ship a replacement and open a failure analysis loop.

Buyer Types We Work With

AGV and mobile robot builders needing consistent 24V / 48V drive motors
Conveyor and sortation OEMs standardizing on a single frame family
Packaging machine builders needing torque-controlled BLDC drives
Medical and lab equipment makers sensitive to noise and reliability
System integrators sourcing motor + controller + gearbox as one package
Distributors and trading companies supplying regional industrial markets
