If electric cars are to be mass produced what type of motor?
Answer
Electric cars can use AC or DC motors... If the motor is a DC motor, then it may run on anything from 96 to 192 volts, if it is an AC motor, then it probably is a three-phase AC motor running at 240 volts AC with a 300 volt battery pack. DC installations tend to be simpler and less expensive.

How are electric car motors cooled? What maintenance is required?

Do electric car motors need fans, radiators, and coolant? How are they cooled? Do they have oil that needs to be changed? How about air conditioning? If there is no radiator or heater core, how can the car be heated? What kind of transmission system do they use? Are they fwd or rear wheel drive? What kind of maintenance is required and how long can an electric motor be expected to last? Are they easy to replace? How do maintenance costs compare to a gasoline engine? Do they require something like a tune up and if so, what would that involve? How difficult are they to work on?
Answer
Q:Do electric car motors need fans, radiators, and coolant? How are they cooled?
A:Electric motors are often air cooled, by a simple electric fan. No coolant is needed for the motor.
Q:Do they have oil that needs to be changed?
A:No.
Q:How about air conditioning?
A: EVs with an air conditioning system are powered electrically in most cases, so there is no belt to replace. Other air conditioning needs is the same.
Q: If there is no radiator or heater core, how can the car be heated?
A:There is no heater core, or radiator as typically used, they are often heated with a simple ceramic heater element, much like a home space heater.
Q: What kind of transmission system do they use?
A: Most conversions use the manual transmission that is on the original vehicle, others (including manufactured EVs) don't use a transmission at all.
Q: Are they fwd or rear wheel drive?
A: Either.
Q: What kind of maintenance is required and how long can an electric motor be expected to last?
A: DC brushed motors need to have the brushes changed every 5 years or so (about as difficult as changing brake pads). Armature bearing may need replacement after much longer. Aside from that an electric motor can last even 100 years in some cases.
Q: Are they easy to replace?
A: Depending on where the motor is, yes. Assuming you have access the motor, they are pretty easy to replace. Disconnect 4 wires, unbolt maybe 6 bolts, pull it out.
Q: How do maintenance costs compare to a gasoline engine?
A: After all is said and done (including batteries) the maintenance cost is about 1/3 that of a traditional gas car, and the technology is getting better and cheaper.
Q: Do they require something like a tune up and if so, what would that involve?
A: Aside from brakes, tires and the other shared components; Motor brushes every 4-5 years (I was quoted $60 to have that done at a local shop). Batteries every 4-6 years for lead acid or every 10+ years for lithium. That's about it.
Q:How difficult are they to work on?
A: Not difficult. They are easier to work on than a gas car (I've done both), but the problem is finding somewhere you can learn the skills.
