Before Tesla existed, enthusiasts were doing conversions on a variety of cars to turn them to an all-electric drivetrain. Most of these used traction motors that you'd find in fork trucks on under railway rolling stock.
There are a couple of limitations with these motors. As other comments have noted, all motors need to have a current that rotates relative to one of its components, the armature, which in the case of a DC motor is the rotor, and this is achieved by the commutator - the cylindrical copper component on the left end.
The brushes (made of a carbon and metallic composite) that run on the commutator are subject to wear, and would require replacement, probably several times during the life of a typical vehicle, so this is the first disadvantage. The construction of the armature, and especially the commutator poses a maximum speed limit on the motor, before you risk the assembly bursting - windings or commutator bars flying out, which is fairly catastrophic, since it'll destroy pretty much all of the motor. Since the maximum torque you can get out of a motor is dictated by the rotor volume, and the flux density you can achieve, the way to get maximum power out of a given size of motor is to run it as fast as it will physically tolerate. BLDC motors, which have no windings on the rotor, can be made to run at much higher speeds. The windings on induction motor rotors are usually a squirrel cage made from bars either cast through the laminations or fabricated from rods, and again can be made to tolerate high speeds.
That leads to the inevitable issue with higher power density - the need to cool the motor. Since BLDC and induction motors have the windings on the stator (this is now the armature, since it is fed by currents alternating in a fashion to produce a rotating field), it'a far easier to fluid cool this - commutator motors are mostly air cooled, though a few low voltage types can run with the rotor submerged in non-conducting fluids - though generally at low speeds.
Overall, given the weight incentive to have higher power density, and the need for lowering maintenance, DC motors are not a good choice for EVs.
As the number of EVs continues to soar (one EV sold every 60 seconds in July 2023), the need for accessible and efficient charging infrastructure is becoming more and more apparent.
While home charging remains a convenient option for many electric vehicle (EV) owners, commercial locations, such as businesses, shopping centres, and car parks, have begun to play a pivotal role in expanding the EV charging network while simultaneously bringing benefits to stakeholders in businesses.
But what exactly are the benefits of having commercial EV chargers at your business premises?
In this blog, we explore the benefits of installing business electric vehicle chargers at commercial locations, examining how these chargers not only serve as a practical amenity for EV drivers but also contribute significantly to sustainability efforts, business growth, and enhanced customer experiences.

Installing EV chargers for businesses can create a new revenue stream. Whether you opt for rapid chargers or fast chargers, you can charge customers or visitors a premium per charging session using a back office management system and generate a new revenue stream for your business.
Over time, you’ll likely recoup your investment and even earn a profit, especially with the help of government grants available for commercial EV charger installation.
With the number of electric cars on UK roads soaring – 1,000,000 fully electric cars and 600,000 hybrids, to be exact – soon, offering employees and visitors somewhere to charge their electric vehicles will become the norm.
By installing EV chargers for business now, you can enhance your brand image and gain a competitive edge. Even one charger can make your business an example of corporate social responsibility and customer-centric thinking.
Demonstrating a commitment to sustainability is vital in today’s business landscape with the looming threat of global warming. Not only does making the switch to zero emissions vehicles signal that your business is environmentally conscious by emitting fossil fuel usage, but installing commercial EV chargers further aligns with your sustainability goals and reduces your carbon footprint. This commitment can improve your brand image and attract an environmentally conscious audience, expanding your customer base.
In fact, you could invest in solar electric car chargers and decrease your businesses’ carbon emissions further by using renewable energy to charge your electric car.
Offering electric car charging stations, especially with a customer-friendly pricing strategy, demonstrates your commitment to accommodating all clientele and customer satisfaction. This can foster loyalty among your customers, giving them a reason to return to your business time and time again.
The initial cost of installing EV chargers at commercial locations can often be a hurdle. However, there are substantial government grant incentives available for the commercial market, making it more financially feasible to install business EV chargers. The Workplace Charging Scheme (WCS) and the EV infrastructure grant for staff and fleets provide thousands of pounds worth of savings for businesses in relation to installing electric vehicle charge points.
As OZEV-approved installers, we can handle all grant paperwork on your behalf.
In summary, the advantages of commercial EV chargers extend beyond providing a convenient service for electric vehicle owners. They offer businesses an opportunity to generate revenue, stay competitive, showcase sustainability efforts, access grant incentives, attract more visitors, and build a loyal customer base. In an age where sustainability and innovation are paramount, the installation of commercial EV chargers can be a game-changer for businesses looking to thrive as the EV market continues to grow.
