RICHTEK hairpin motor: Powering a Revolution in Short-Distance Transportation

1

Technology Driven

A Power Upgrade Starting from the Streets

In the morning markets of Hanoi, Vietnam, a tricycle loaded with 600kg of seafood is forced to shut down due to motor overheating; on the streets of Bangalore, India, an electric motorcycle rider charges three times a day due to insufficient range – 2 billion short-distance transportation workers worldwide are facing a collective anxiety about power systems.

RICHTEK breaks the deadlock with its hairpin motor technology. The 100/128/145 series, specifically developed for electric motorcycles and electric tricycles, redefines industry standards with three sets of hardcore data:

► Load capacity increased by 110% ► Range extended by 35% ► Failure rate under extreme conditions < 0.3%

The Overwhelming Advantages of Flat Wire Technology

☌ Load Capacity Revolution

Through four-layer flat wire winding, current carrying capacity is increased by 2.8 times. RICHTEK R&D center tests confirm:

→ Electric tricycle carrying 1000kg climbing a 10° slope, power consumption reduced by 27%.

→ Motor shaft torsional strength increased by 40%, meeting the overload modification demands of Southeast Asian markets.

☌ Range Disruption

Dual technologies of 3D heat dissipation and energy recovery. User tests in Africa show:

→ 72V120Ah battery achieving a range of 182 kilometers.

→ Braking energy recovery contributing 15% to range, saving over 900 RMB in electricity costs annually.

☌ All-Weather Reliability

IP67 protection: Tested during Indonesia's typhoon season, operating continuously in 50cm deep water for nearly 1 hour.

Wide temperature range adaptation: Cold start in -30°C Heilongjiang in < 3 seconds; full load operation in 60°C Sahara heat without power reduction.

☌ Economic Breakthrough

→ Save enough in three years to buy a new vehicle: In daily 200km operational scenarios, comprehensive operation and maintenance costs reduced by 64%.

→ Residual value rate increased by 45%: Clear premium for hairpin motor models in the secondary market.
