A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures.

The first electric golf cart was custom-made in 1932, but did not gain widespread acceptance. [3] In the 1930s until the 1950s the most widespread use of golf carts was for those with disabilities who could not walk far. [4] By the mid-1950s the golf cart had gained wide acceptance with US golfers. [5]
When braking in the drive system is needed, the motor flux and thus also the magnetizing current component used in the motor are increased. The control of flux can be easily achieved through the direct torque control principle. With DTC the inverter is directly controlled to achieve the desired torque and flux for the motor. During flux braking ...
Electric park brake in the center console in a Volkswagen Golf Variant. An electronic parking brake (EPB), also known as an electric parking brake or electric park brake, is an electronically controlled parking brake, whereby the driver activates the holding mechanism with a button and the brake pads are electrically applied to the rear wheels.

The disadvantage of this feature is that it wears the brushes prematurely when compared to non-brake tools. The first use of an electric brake on a tool was that of the miter saw, invented in 1964 by Ed Niehaus, a tool engineer for Rockwell Tools. Since then, a number of manufacturers have incorporated brakes into their power tools.
Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...
DC injection braking unit, an electrical braking device for ac motors; Regenerative braking unit, regenerative braking systems used in traction motors; Electromagnetic brake, devices using electromagnetic forces to mechanically brake; Braking chopper, an electronic switch used to dissipate high voltage in an intermediate circuit
A brake controller is usually an original equipment manufacturer or aftermarket-installed device or module. It is mounted to the tow vehicle's driver's-side dashboard area, and engages a trailer's electrical braking system either time delayed, or in proportion to the tow vehicle's brake engagement when slowing down or coming to a halt.
