This electric bike is shaft-driven. Moreover, it’s assisted by an oversized rear hub that cleverly conceals a 250W motor; sensors to measure torque, slope, and cadence; controller; Bluetooth ...

O.G. Schmidt invented the electric trolling motor in 1934 when he attached the starter motor from a Model A Ford to a flexible shaft with a propeller on the end. A fanatical angler, Schmidt used the ...

It has been a long haul, but I finally have the motor in my ’67 Beetle EV conversion. I’ve had one setback after another, but I expected it to be the most technically challenging part of the ...

Machinery manufacturers often use electrically insulated couplings in their equipment to prevent arcing across bearings and other components, Figure 1. The arcs result from electric motor shaft ...

Electric car motors work by mounting one set of magnets or electromagnets to a shaft and another set to a housing surrounding that shaft. By periodically reversing the polarity (swapping the north ...

Most internal combustion engines have a maximum of about 6,000 rpm. But an automobile's electric motor might spin as fast as 9,000 rpm. Nitz said that speed presents engineering challenges.

Electric motors use electromagnetic force to produce movement. Magnetic forces — attraction and repulsion — cause the electromagnet inside an electric motor to spin.

Donut's 150 kW, 17-inch motorcycle motor is already in use on the road for a few boutique electric bikes, so the odds of seeing this tech on a car in the future is better than you might think.

By packing everything into the wheels, there’s no need for other components like a gearbox or a drive shaft which usually transfers power from the onboard motor to the wheels. This makes the car ...

Mitsubishi Electric has begun mass-producing the first crankshaft-mounted integrated starter-generator system for 48V hybrid systems. This system will be used by Mercedes-Benz and is on display at ...

This version equals its sibling in the weight department but boasts an 11.01-kW (16-kW peak) Jante motor for up to 456 Nm (336 lb.ft) of torque on the rear wheel and up to 76 Nm on the shaft.
