Glossary of torque motors and alternators

 

Torque motor and high torque motor

A torque motor is an electric motor which is used in low speed applications and generally in direct drive without gearbox. This is the reason why they are also often referred to as high torque motors. In addition, torque motors are often incorporated into cyclic production machines with acceleration, speed, deceleration and sometimes reversal, in contrast to the applications of machines with continuous operation delivering power at constant speed. ALXON is present in this field with the complete torque motors ST and motors in kits to integrate STK

 

Motor or alternator for direct drive

A motor or alternator for direct drive is a motor which is directly coupled to its load or an alternator to its drive motor or a turbine without the use of gearbox or speed multiplier. ALXION ST complete torque motors and STK torque motors and alternators in roto-stator kits are generally used in direct drive motors.

 

Frameless rotor or alternator

A frameless motor or an alternator  consists of 2 parts: a stator and a rotor which are intended to be integrated into the user’s mechanics. Motors and alternators in roto-stator kits are particularly recommended to optimize technically and economically the direct drive applications without reduction gear or speed multiplier thanks to the compactness, the precision, the dynamic performances and the reliability that they allow. ALXION is present with its range of STK frameless torque motors and alternators in roto-stator kits.

 

Wind turbine

A wind turbine is a machine converting the wind energy in mechanical energy then in electrical energy. The energy conversion is made by a turbine driving an electrical generator. The optimization of a wind turbine is aimed at maximizing the efficiency of the wind / mechanical  then mechanical / electrical energy conversion as well as starting with a low wind speed.
There are horizontal axis or HAWT and vertical axis or VAWT wind turbines. ALXION STK Permanent Magnet Generators or Alternators equip both horizontal and vertical axis wind turbines.

 

Small wind turbine

A small wind turbine is a « wind turbine » of low power rate. Typically, the expression « small wind turbine » is used for electrical power ratings up to 100 KW maximum. ALXION is present in the segment of small wind turbines of less than 100 KW with its STK alternators which make the mechanical / electrical energy conversion.

 

Wind turbine alternator

A wind turbine alternator is an electrical machine making the conversion from mechanical energy to electrical energy in a wind turbine (see that word ). The excitation of the alternator or inductor is generally effected by permanent magnets at the rotor. Alternators with external stator are more powerful in power-to-weight because the cooling of the stator windings is more efficient when the stator is in contact with the air. STK ALXION alternators have an external stator and an internal rotor and are excited by high-energy rare earth permanent magnets at the rotor.

 

Wind turbine generator

A wind turbine generator is an electrical machine making the conversion from mechanical energy to electrical energy in a wind turbine. The excitation of the alternator or inductor is generally effected by permanent magnets at the rotor. Alternators with external stator have a higher power-to-weight because the cooling of the stator windings is more efficient when the stator is in contact with the air. STK ALXION alternators have an external stator and an internal rotor and are excited by high-energy rare-earth permanent magnets.

 

Windmill alternator

A wind turbine or windmill alternator  is an electrical machine making the conversion from mechanical energy to electrical energy in a windmill or wind turbine). The excitation of the alternator or inductor is generally effected by permanent magnets at the rotor. Alternators with external stator are more powerful in power-to-weight because the cooling of the stator windings is more efficient when the stator is in contact with the air. STK ALXION alternators have an external stator and an internal rotor and are excited by high-energy rare earth permanent magnets at the rotor.

 

Windmill generator

A wind turbine  or windmill generator is an electrical machine making the conversion from mechanical energy to electrical energy in a windmill or wind turbine. The excitation of the alternator or inductor is generally effected by permanent magnets at the rotor. Alternators with external stator have a higher power-to-weight because the cooling of the stator windings is more efficient when the stator is in contact with the air. STK ALXION alternators have an external stator and an internal rotor and are excited by high-energy rare-earth permanent magnets.

 

Permanent Magnet Generator

A permanent magnet generator is a device that converts mechanical energy to electrical energy. AC Alternative current generators are also referred to as alternators. The generator inductor is usually made today with permanent magnets. ALXION produces three-phase permanent magnets generators ; See the range Alternators STK

 

Permanent magnet alternator

An alternator is an electrical generator converting mechanical energy into AC alternative current  electrical energy. In an alternator with magnets, the excitation of the alternator is made by permanent magnets connected to the rotor (inductor). Permanent magnet alternators with external stator have a higher power-to-weight because the cooling of the stator windings is easier when the stator is in contact with the ambient air. ALXION STK alternators have an external stator and an internal rotor and are excited by high-energy rare earth permanent magnets.
