Bosch debuts new CV-specific electric motor and inverter
A new Bosch electric motor paired with an advanced power
inverter bring an integrated propulsion solution to the commercial
vehicle (CV) market. " Electrification is the future,
and we think there's going to be a wide variety of e-powertrains
for the medium-duty segment in the very short
term, " said Dr. Shyam Jade with Bosch in North America.
Jade, a senior engineer of control system development for
electrified vehicle system engineering, recently spoke with
SAE Media. " This new e-motor is an enabler, whether it's for
a full electric, a hybrid or a fuel-cell commercial vehicle, "
Jade said. The motor's debut coincides with the company's
40% investment increase, year-over-year, in e-mobility.
The 230 motor gets its name from its stator diameter - 230
mm (9.05-in.). " The e-motor is slightly bigger than what you
see in a typical passenger electric vehicle. But it's significantly
smaller than a typical gasoline or diesel engine, " Jade said,
noting the e-motor's compact size and other attributes will
appeal to the CV market.
Battery-electric CVs are a rarity in 2021, with less than 1%
of the medium-duty and heavy-duty vehicles (Classes 4-8)
claiming the designation, according to Kenny Vieth, presiThe
Bosch product
portfolio for commercial
vehicles includes an
advanced inverter with
silicon carbide technology.
dent and senior analyst for ACT Research, a firm that provides
data, industry analysis, and forecasting services for CV
and transportation markets. By 2026, battery-electric adoption
is expected to reach 11%. " But there are material differences
in adoption between medium-duty Classes 4-7 and
