A description of ac motors

A totally enclosed non-ventilated TENV motor enclosure limits the flow of air into the motor, but is not airtight. However, a seal at the point where the shaft passes through the housing prevents water, dust, and other foreign matter from entering the motor along the shaft.

Sorry! Something went wrong!

A later version, called EPIC, was sold starting in ; it had double the voltage of the first one, extending the range past 50 miles, and switched to an advanced lead-acid battery pack.

Chrysler had also worked on electric cars back in the s, producing in cooperation with Jet a four-passenger electric city car, which were purchased by some organizations but apparently never officially sold. Likewise, the Neon was originally to be sold in diesel and electric versions.

Even more prescient, or at least more determined, was the Tag 2 group in Livonia, Michigan, a group of engineers that produced their first electric vehicle in Mike Hofer, a North Dakota businessman, recognized the potential of the little car, and assembled a group of investors.

He then purchased the company and moved the entire operation to Fargo in December of The Fargo factory manufactured its first vehicle in April The volt GEM could accommodate two passengers and had a top speed of just 20 miles per hour; however, less than two months later, a breakthrough in market conditions occurred when NHTSA National Traffic Safety Administration designated a new class of motor vehicles: Those living in the denser environs of the city would probably want transportation other than the bus sometimes.

In November ofthe first utility version of the GEM was produced. These became part of the fleet of utility vehicles at Luke Air Force based, the largest fighter pilot training facility in the world, near Phoenix, Arizona; as ofthere were GEM vehicles in service at Luke, out of a fleet of vehicles.

By the end oftotal production reached 1, vehicles; and by the end of Junethe monthly output had surpassed vehicles. By the end of Decembertotal production had hit 5, vehicles. At that time, a past Chrysler executive joined up with a competing electric-car company.

Some claim it was out of spite that DaimlerChrysler quickly acquired GEM; others claim that it was, as DaimlerChrysler said, a matter of building zero-emission vehicles to supplement the slow, expensive research into hydrogen power.

Bythe GEM line of vehicles included both two and four passenger electric vehicles, as well as two utility vehicles with short and long boxes.

The curb weight of the two passenger machine was just 1, pounds, including batteries; while the curb weight of the long box utility vehicle was just pounds more. Power was the same for the GEM fleet: But the major selling point was the proprietary volt DC on-board charger, which employed the standard volt AC house current.

They had plenty of torque, a hallmark of electric vehicles, and good handling, partly because of the independent front suspension and rear trailing-arm suspension. Rack and pinion steering gave a precise feel; having the batteries close to the ground probably helped the stable feel.

The width of just 55 inches was akin to — well, a golf cart. The range of these vehicles was about 30 to 35 miles, dependent upon ambient temperature and terrain, enough for local grocery shopping or even typical commuting; when stopped, the GEMs consume barely any power, so stop and go traffic is not a problem.

The rise of the price of oil has only helped GEM.

The battery pack in the current GEM vehicles is the gelatin type, with low maintenance. The steering geometry has been reworked to allow even more precise steering; and the responsive of the electric motor is better.

There are even performance upgrades for GEM cars and utility vehicles. Orange County and San Francisco, places that are friendlier to electric cars, have done even better.

The nice thing is you can call the manufacturer up in Fargo. While there is still a proprietary on-board charger for GEM cars, they do, after all, have to plug into something.

Normally, utilities see peak demand during the day, and they need to have extra powerplants to fill that demand; but those plants often sit idle at night, an apparently needless expense.Siemens is the number one provider of motors worldwide, with global service and support second to none.

Siemens offers both NEMA and IEC (metric) motors and features a line of copper rotor motors for those seeking even higher efficiencies.

The DRV provides a 4-channel low side driver with overcurrent protection. It has built-in diodes to clamp turnoff transients generated by inductive loads and can be used to drive unipolar stepper motors, DC motors, relays, solenoids, or other loads.
