DC Motor Guide: Pancake, BLDC & Wheel Hub Motors from Wuxi Speedup

DC Motor Guide: Pancake, BLDC & Wheel Hub Motors from Wuxi Speedup

Selecting the right DC motor is critical for performance, efficiency, and durability across industrial and civil applications. This guide provides an overview of three prominent DC motor types — pancake motors, BLDC motors, and wheel hub motors — using verified specifications and real-world application data from Wuxi Speedup Power Co., Ltd., a specialized manufacturer with over 16 years of industry experience.

Problem Definition: Matching Motor Architecture to Application

Engineers and procurement professionals face decisions around space constraints, torque requirements, speed range, efficiency, control complexity, and environmental resistance. Each motor type offers distinct characteristics: pancake motors excel in flat, compact spaces; BLDC motors offer high efficiency and long life; wheel hub motors integrate propulsion directly into the drive wheel. Understanding these differences helps narrow the selection.

Industry Background

The global brushless DC (BLDC) motor market was estimated at USD 20.99 billion in 2024, with China accounting for approximately 39.8% of revenue (Grand View Research). The electric wheelchair market, a key application for wheel hub motors, was valued at USD 4.49 billion in 2024 and is projected to reach USD 9.05 billion by 2030. These trends reflect growing demand for efficient, compact, and reliable DC motor solutions across mobility, medical, and automation sectors.

Wuxi Speedup Power Co., Ltd., established in 2018, operates a 10,000 m² facility with an annual production capacity of 30,000 units. The company's R&D team of 3 engineers focuses on custom configurations, exporting 90% of products to EU and USA markets.

Detailed Solution: Three DC Motor Architectures

1. Pancake Motors (Printed Armature / Disc Motors)

Pancake motors use a flat, printed armature design that allows a compact axial profile. They deliver high power-to-volume ratio and excellent linearity. Wuxi Speedup offers both brushed and brushless pancake variants:

• Model 128SN – Brushed DC, 18V / 135W / 2100 rpm, diameter 148.5 mm, thickness 37 mm, axis length 21 mm (customizable). Made of aluminum alloy, copper, and rare earth NdFeB permanent magnets.
• Model 150SN-A – Brushed DC, 36V / 300W / 3500 rpm, diameter 151 mm, thickness 35.4 mm. Designed for floor washing machine brush drives.
• Model 150SN-B – Brushed DC, 24V / 350W / 3000 rpm, same 151 mm diameter. Used in burnishers and polishers.
• Model 150SN-G2 – Brushed pancake with gearbox, 36V / 500W / 22 Nm / 240 rpm. Ideal for high-torque low-speed applications.
• Model DD03 – Brushless DC (BLDC) direct drive, 24V / 100W / 250 rpm, 106 mm diameter, 51 mm length. Used for cleaning machine brush drives and other continuous duty cycles.

2. BLDC Wheel Hub Motors (Brushless Hub Motors)

These outer‑rotor motors integrate Rare Earth NdFeB Permanent Magnets, offering high efficiency, long service life, silent operation, and IP54 protection in many models. They are available in solid or pneumatic tire configurations:

• Model SA05-6 (6.5") – 24V / 200W / 150 rpm / 15 Nm, gear ratio 1:4.5, IP54, electronic brake (EABS). Suitable for wheelchair assistance, AGV, medical chairs.
• Model SA06 (12") – 24V / 300W / 150 rpm / 20 Nm, gear ratio 1:4.5, IP54, EABS or disc brake. Used in mobility scooters, electric scooters, folding e‑bikes.
• Model 1DY-E5S (8") – 36V / 300W / 150 rpm / 20 Nm, gear ratio 1:20, electromagnetic brake. Designed for mobile scooters, wheelchairs, AGVs.
• Model SA05 – spoke type, 24–48V / 100–500W / 100–500 rpm, gear ratio 1:5. Customizable shaft and adapter plate for any wheel size. Used in e‑bikes, snowmobiles, garbage trucks.

3. Brushed Wheel Hub Motors (Geared Hub Motors)

Brushed DC hub motors are cost‑effective solutions for medium‑duty applications. They typically incorporate a reduction gearbox and an electromagnetic brake (EMB):

• Model 1DY-E3 (8") – Brushed DC, 24V / 180W / 95 rpm / 20 Nm, gear ratio 1:20, EMB brake. Used in electric scooters, shopping carts, hospital transport beds.
• Model 1DY-E5A (8") – Brushed DC, 24V / 300W / 100 rpm / 30 Nm, gear ratio 1:20, EMB brake. Suitable for hospital beds and light electric vehicles.
• Model 6DY-A (spoke type) – Brushed DC, 24V / 300W / 70 rpm / 40 Nm, gear ratio 1:40, EMB brake. Loading 80–300 kg. Used in dustcarts, wheelchairs, municipal electric vehicles.
• Model 6DY-A4 (12") – Brushed DC, 24V / 200W / 70 rpm, gear ratio 1:40, EMB brake with manual clutch. Designed for electric wheelchairs and medical carts.
• Model 6DY-A1 – Magnesium alloy integrated wheel, 24V / 200W / 65 rpm / 28 Nm, gear ratio 1:40, folding brake clutch lever. Offers superb climbing ability.
