If the horsepower requirements of the intended connected load fall between standard size horsepower ratings, it is generally better to install an electric motor of the next higher horsepower rating and operate it under load, rather than depend on operating the motor in the service factor range to attain the required horsepower rating. A frame 145T frame, listed in Figure 1, would have a shaft height of 3.5 inches (14 divided by 4) above the mounting base of the motor. Features and Benefits The nameplate shown in Figure 1 indicates the serial number this motor is 134678. NEC indicates that the kilovolt-amperes per horsepower at locked rotor for a type J rotor range from 7.1 to 7.99 kVA per HP. To sell his engines, Watt decided to compare the amount of power his steam engine could produce to the working ability of a horse. Top Selling Motors. Electric motors that operate in hotter climates, like near the equator, should have a higher insulation temperature rating as compared to electric motors, which operate near the United States and Canadian border. Rated in “pole pairs”, the synchronous speed of the electromagnetic field rotating about the inner face of a 2-pole motor operating at 60 Hz is 3600 RPMs: 60 cycles/second x 60 seconds/minute = 3600 cycles (rpms) /minute. The nameplate shown in Figure 1 indicates this motor is rated at 1 horsepower. GE. GE rises to the challenge of building a world that works.

Design A        AC induction motors with the design code letter A exhibit normal starting torque, but with high starting current. 6) Efficiency. The nameplate shown in Figure 1 indicates this is a dual-voltage AC induction motor. They operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. The stator winding current will be of low or minimum value; the slip will be near zero, and the delivered torque will be near zero. Electric Motors, GE Motors & Industrial Motor Replacement Parts. Electric motors have a rated horsepower (HP) that is determined by the amount of torque they can produce at their running or baseline speed. If the motor is connected to the high-voltage operation, as indicated by the terminal connections in the wiring diagram to the right on the nameplate, it will operate satisfactorily on 460 VAC. Design D motors also exhibit a large amount of rotor slip when the load is added. The Evolution Series is a line of diesel locomotives built by GE Transportation Systems (now owned by Wabtec), initially designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. Through brushes riding on the slip rings, a 3-phase or “3-leg” wye-connected resistive load bank can control the magnitude of the rotor current. The remaining power is a loss that is converted mostly into heat. With a service factor of 1.15, the motor can be overloaded up to 1.15 horsepower. T   NEMA standardized The T frame motors after 1964. For more information on what General Electric motors can do for you visit them at this link .

The 752 High-Torque DC drilling motor with 2800 SCFM airflow and temperature rise of 155oC at 40C ambient. This process will continue until the %-slip of the slowed rotor reaches about 20%, at which time the AC induction motor will enter breakdown torque and abruptly stop in a locked-rotor condition. These electric motors are not intended for with belt drives. MV Induction Motors 500-7500 HP, 400-5600 kW. Synchronous motors are easily recognized by the two slip rings on the rotor shaft. The new motor will not duplicate the older motor’s winding characteristics (e.g., resistance, inductance, amperage, or regulation). "url": "https://electricala2z.com/category/motors-control/", The nameplate shown in, Induction motors have different operating characteristics determined by their design. Monterrey, Mexico The nameplate shown in. Some of the common enclosures include: Explosion-proof (EXP) — these enclosures are designed for areas that have hazardous atmospheres; the end bells and the cylindrical motor housing are totally enclosed and non-vented.eval(ez_write_tag([[300,250],'electricala2z_com-large-leaderboard-2','ezslot_10',110,'0','0'])); Open Drip Proof (ODP) — these enclosures are probably the most common used. 3 Pages. No. { The XSD Ultra® family of products ranges from 1-300 HP and is built to the highest standards to maximize your return on investment. If the motor leads are configured (connected) to operate at 208 VAC, the AC induction motor should draw 3.6 amperes when operating at full load. Another factor is the design of the motor itself. The allowable overloading is determined by multiplying the horsepower rating on the nameplate by the service factor. Enclosure: TEFC. The induced voltage causes current to flow in the shorted rotor windings. DC Motors: Learn more. 12) Time rating. Each item on the nameplate shown in Figure 1 will be discussed. This designation specifies the length of time that the motor can safely … Operated at no load, the actual speed of the turning rotor will be close to the synchronous speed of the stator circuit’s rotating electromagnetic field. © Copyright 2020 GlobalSpec - All rights reserved.
