YASA is a British manufacturer of electric motors and motor controllers for use in automotive and industrial applications.[1][2][3] The company was founded in 2009 by the CTO Dr Tim Woolmer who is also the holder of a number of related motor technology patents.[4] Although initial commercial adoption was in high-performance cars, markets for YASA e-motors and generators now include the off-road, marine, industrial and aerospace sectors.

History

YASA Limited (formerly YASA Motors Limited) was founded in September 2009 to commercialise a permanent-magnet axial-flux electric motor (YASA stands for yokeless and segmented armature). The motor was developed for the Morgan LIFEcar in 2008 by Dr Malcolm McCulloch and Dr Tim Woolmer, then a PhD student, at the University of Oxford.[2][4][5] In 2015, YASA Motors launched the P400 Series of motors in serial production for volume manufacturers.[6] In January 2018, YASA's 1st series production facility, capable of 100,000 units per year, was officially opened[7] by the Rt Hon Greg Clark, UK Secretary of State for Business, Energy and Industrial Strategy

Products and applications

YASA 750 e-motor/generator. 790 Nm from 37 kg.

YASA offer a range of off-the-shelf and custom motors for use in a number of applications such as electric (BEV) and hybrid vehicle drivetrain,[8] power generation and hydraulics replacement systems.[9][10]

Standard Motors

YASA's standard electric motors have been used in several high-performance cars such as the Drive eO PP03, Jaguar C-X75, Koenigsegg Regera,[11][12][13] and a Lola Le Mans Prototype converted by Drayson Racing, which set a world electric land speed record in 2013.[14][15][16]

YASA P400 Series

The YASA P400 series of electric motors produces up to 160 kW (210 hp) peak power at 700 V and 370 N⋅m (270 ft⋅lb) of peak torque @450 Amps.[17] At this peak power, the off-the-shelf P400 Series achieves a power density of 6.67 kW/kg (4.06 hp/lb), with continuous rating of up to 100 kW (130 hp). The stator of the P400 series motors is oil cooled, and can optionally include an auxiliary air cooler.[17]

YASA 750 R

The YASA 750 R is the larger and more powerful electric motor in YASA's standard range, producing up to 200 kW (270 hp) of peak power at 700 V and 790 N⋅m (580 ft⋅lb) of peak torque. Continuous operating power for the 750 R is stated at up to 70 kW (94 hp).[18]

Custom E-Motors

As well as standard products, YASA designs and manufactures e-motors that are fully integrated into the drivetrain of their OEM and Tier 1 automotive customers. The e-motors feature power densities up to 15 kW / kg[19] in vehicle applications that include P2 Hybrid Vehicle Powertrain[20], P4 traction motor for e-axle[19] and REx (range-extension)[21].
