Strict 100% Quality Control Framework
Quality is the foundation of our business. To ensure output consistency and product reliability across every order batch, we enforce thorough inspection procedures throughout manufacturing:
- Incoming Quality Control (IPQC): 100% inspection of raw materials and parts (gears, gearboxes, housings), checking dimensions, hardness, surface roughness, and mechanical strength.
- In-Process Inspection: 100% on-site inspection and routing checks for rotors, stators, commutators, axial endplay, and electrical performance.
- Outgoing Quality Control: Final sampling inspection before shipment, combined with high-grade protective packaging to prevent transit damage.
Important Operation and Installation Guidelines
To maximize service life and prevent accidental damage during installation or operation, please follow these guidelines:
- Shaft Machining Restrictions: Do not machine or alter the motor shaft without prior authorization from our engineering team, as external force can strip internal gears.
- Motor Mounting Orientation: The standard installation orientation is horizontal shaft positioning. Changing the tilt angle may lead to lubricant leakage or altered shaft loads, affecting performance and lifespan.
- Avoid Manual Shaft Rotation: Do not forcibly turn the output shaft by hand during installation. Back-driving turns the gearbox into a speed multiplier and forces the motor to act as a generator, which can strip gears or damage driving circuitry.
- Terminal Soldering Rules: When hand-soldering wire leads to motor terminals, maintain iron temperatures between 350°C and 400°C and complete soldering within 2 to 3 seconds. Excessive heat transfers down the terminal and melts internal brush holders.
- Prevent Continuous Stall & Overload: Heat generated under rated load dissipates naturally during operation. Frequent stalls or severe overloads rapidly overheat the motor, melting coil insulation and burning out the armature.
- Managing Inertial Spin-Down: When power is disconnected, rotational inertia causes the shaft to coast for a few seconds. To achieve instant stopping, connect the positive (+) and negative (-) terminals together to trigger dynamic braking via inverse generator current (note: frequent dynamic braking slightly reduces motor lifespan).
