- Wallace's main scientific interest was the synthesis and characterization of permanent magnet motors today.
- Recent innovations include permanent magnet motors, machine room-less rail mounted gearless machines, and microprocessor controls.
- Permanent magnet motors have been in existence since the introduction of electric motors more than one-hundred years ago.
- The higher starting torque of those appliances with a permanent magnet motor ensures in most cases that there will be no blockage.
- These systems may use thyristors, inverters, permanent magnet motors, or various hybrid systems that incorporate PWM systems and standard motors.
- For permanent magnet motors, dynamic braking is easily achieved by shorting the motor terminals, thus bringing the motor to a fast abrupt stop.
- As part of the design phase, Northrop Grumman had built the world's largest permanent magnet motor, designed and fabricated by DRS Technologies.
- Permanent magnet motors use a permanent magnet ( PM ) in the rotor and operate on the attraction or repulsion between the rotor PM and the stator electromagnets.
- Still widely used, universal traction motors have been increasingly displaced by polyphase AC induction and permanent magnet motors with variable-frequency drives made possible by modern power semiconductor devices.
- In addition, an on-shaft permanent magnet motor drive system also utilizing gas turbine Prime Movers on the main reduction gear, can also provide electricity when driven by the Prime Movers.
- A 36 volt electrical system ( operating at 42-45 Volts ) is used to operate a permanent magnet motor / generator unit mounted to the engine in a similar fashion to a conventional alternator.
- A special automatic transmission ( designated as a 2ML70 by General Motors ) incorporates two 82 kW ( 110 hp peak ) three phase permanent magnet motors, three planetary gear sets, and four selectively engaging friction clutches.
- Your model and photograph would be fine illustrating " a simple DIY DC permanent magnet motor " ( demonstrating that it is not necessary to reverse the current flow, but only to switch it of for 180?).
- This two facts, in addition to the cheaper price of a permanent magnet motor with respect to a standard DC motor ( as a matter of fact only the rotor coils need to be winded ), are the main reasons why armature controlled motors are widely used.
- Many types of permanent magnet motor cannot be disassembled without ruining the magnet . ( When the motor is assembled, other parts of the motor short out the magnetic field . ) This is also the reason why permanent magnets are sometimes stored with an iron " keeper " across the poles.
- :: : : : 87.102.86.73 points out below, that then starts to beg the question of which motors are " AC " motors and which are " DC " motors . ( I also suspect ( but have no proof ) that a modern permanent magnet motor is lighter than an induction motor for a given mechanical power .)
- Oceanvolt has received several awards for its SD8.6 saildrive system, the latest being the 2013 Pittman Innovation Award given by SAIL Magazine for Oceanvolt's " compact robust design " featuring waterproof permanent magnet motor with closed circulation liquid cooling, single lever control with motor status shown by LEDs, and folding propeller which doubles as a hydrogenerator, silently extracting several kilowatts of electric power from the boat's forward motion while under sail.
