7 Custom Motor Options

When many engineers think of a “custom motor,” they often imagine only small adjustments—like changing the voltage rating or extending the shaft length. But a true motor manufacturer like BG Motor can go much further. By working on the mechanical structure, electromagnetic performance, control integration, and environmental protection, we create motors that are perfectly adapted to your equipment instead of forcing your design to adapt to the motor.

Here are 7 powerful customization options you may not know you can request:

1. Shaft Machining – Precision Fit for Seamless Power Transfer

Standard shafts rarely match every machine interface.A mismatch creates the need for adapters, which introduce tolerance errors, vibration, and even premature bearing failure.

At BG Motor, shafts can be customized in diameter, length, step design, keyways, or threads according to your drawings.

• AGV wheels benefit from D-cut shafts that lock securely, ensuring no slippage during acceleration.

• Medical centrifuges require ultra-precise, ground shafts with minimal runout to guarantee balance at high speeds.

This level of customization ensures reliable torque transmission and longer service life for your system.

2. Flange and Mounting Design

We can design flanges, mounting holes, and housing geometries to match your machine’s structure. This makes motor installation seamless, reduces assembly space, and eliminates the need for redesigns.

3. Speed and Torque Characteristics – Designed for Your Duty Cycle

Not every application runs the same way. Some require high starting torque, others need steady low-speed performance. Off-the-shelf motors often fail to meet these unique load profiles.

With electromagnetic design expertise and simulation tools like ANSYS, JMAG, and MotorCAD, BG Motor engineers can tailor the torque–speed curve of your motor.

• Robot arms need smooth, low-speed torque for precise positioning—something we achieve with optimized winding and planetary gear integration.

• Industrial lifting systems require motors with high peak torque and thermal protection for repetitive heavy-duty cycles.

Instead of compromising your design, BG delivers a motor that fits your duty cycle perfectly.

4. Protection Grade (IP Rating)

Dust, water, and harsh environments can quickly damage motors. With customized IP65, IP67, or IP68 sealing, your motor can handle outdoor, medical, or cleaning equipment applications without performance loss.

5. Thermal and Insulation Options

By using different insulation classes (B, F, H) and advanced thermal-resistant materials, we can ensure stable operation in high-temperature environments. Optimized heat dissipation paths prevent overheating, increasing durability.

6. Control Integration

We can integrate encoders, drivers, or electromagnetic brakes directly into the motor housing. This gives you a complete mechatronic system, saving integration time and guaranteeing compatibility. Ideal for AGVs, robotics, and automated production lines.

7. Environmental and Noise Control

For applications where comfort and precision matter—such as medical devices, smart home equipment, or office machinery—we optimize bearing selection, rotor balance, and housing stiffness. The result: low-noise, low-vibration motors that run smoothly and quietly.

The BG Motor Advantage

Customization is not just a service at BG—it’s our engineering philosophy. With:
