Why YASA Axial Flux Motors are the perfect fit for the Marine Electrification Sector

25 July 2024

After a very successful trip to Electric & Hybrid Marine Expo in June, our Senior Business Development Manager Jon Whitehouse  met with Matt Ross from Electric & Hybrid Marine Technology, to talk about how the YASA axial flux motor technology is perfect for the burgeoning marine electrification sector.

Many may not realise that YASA has been active in the marine sector for more than a decade and has been involved in pure-electric propulsion, hybrid propulsion, generation and auxiliary systems projects. One of our earliest marine projects was supply of a lightweight motor to Griffon Hoverwork.

Jon Whitehouse says:

"As in the automotive market, our focus is on high performance. We are known for supplying highly-power, dense, compact, lightweight motors to companies such as Ferrari for their first hybrid supercar, the Stradale SF90. That same power-dense axial flux motor technology is now bringing new levels of performance to small craft marine propulsion."

"A great example of pushing the boundaries of marine performance was our work with Williams Advanced Engineering  and Jaguar on the Jaguar Vector V20E. In 2018, Jaguar set the electric water speed record on Coniston Water in England’s Lake District after the boat recorded a top speed of 88.61mph (142.60km/h)"

Many of the characteristics of YASA's axial flux motors, lend themselves to use in marine systems, the most obvious being the compact & lightweight design,  however for marine applications there are other critical attributes, including:

  • The optimally short axial length: helps deliver a very compact hybrid powertrain, maximizing aft cabin space in a motor cruiser for example.
  • High torque at low speeds: directly enables drive solutions without the need for a gearbox, thereby delivering a lower cost and highly compact solution with greatly reduced noise and vibration levels.
  • Efficient direct cooling: enables high continuous power usage, a key factor needed across many marine propulsion applications.
