general features

MAGNETIC torque motors HTQ series are permanent magnets synchronous motors designed for industrial machines integration. They have been specially engineered to achieve the higher and higher performances required in the automation field by a high torque capability at low speed and by the elimination of the traditional components of the kinematic chain which allows to increase the precision and the efficiency of industrial machines.

The high efficiency typical of these motors makes them particularly suitable even for applications of electricity generation in hydroelectric field and from wind turbines.

In order to meet the market requirements MAGNETIC, on the ground of its experience of many applications in different fields, has designed a new synchronous motors series with high poles number and equipped with last generation magnets made of neodymium, iron and boron.

> personalizzazioni meccaniche (sporgenza d’albero, accoppiamento meccanico
B3, B5, B35 e B14 ecc…) ed elettriche a seconda delle esigenze
> avvolgimento trifase a stella senza neutro accessibile

why use a HTQ motor
  • motion precision
  • high performance with consequent increase of the efficiency due to the reduction of the system frictions
  • reduction of time and maintenance costs resulting from the removal of pulleys, gears and any other mechanical part that needs periodic maintenance.
  • noise reduction by the elimination of mechanical components (pulleys, reducers) and auxiliary ventilation.
  • reduced overall dimensions of the machine due to the reduced dimensions of the motors and the elimination of mechanical components (pulleys, reducers etc.).
  • enhanced integration of the motor on the machine
  • increase of productivity

The use of MAGNETIC HTQ motors allows to reduce the TCO (total cost of ownership), that is the gross amount including all the expenses incured during the life cycle of the equipment: purchase, maintenance, energy for operation, removal.

As an example you can consider an extruder that needs scheduled maintenance of motor and mechanical components (pulley, gearbox) with consequent stop of the machine and production standstill. By means of torque technology this down time is reduced or totally eliminated.

applicazioni
  • wire extrusion
  • machines and extruders for plastics
  • multi axis machine tools
  • lifting winches
  • mini and micro wind turbines and hydroelectric systems
standard rules

HTQ motors are manufactured in fully accordance with standard CEI EN 60034-1 and they comply with IEC 34-1, therefore in accordance with the rules of the main European countries.

insulation

The whole series is dimensioned in F class, the max. overtemperature allowed is therefore 105°C. Anyway, in order to increase the machine reliability, almost all the insulating materials are in class H (Δt max 125°C, absolute max. foreseen temperature 180°C). The impregnation is always double and made under vacuum to guarantee the resin penetration.The winding is made of copper foreseen with special enamel to resist to the peaks generated by the inverter (high voltage variations, dv/dt). In any case it is advisable to contain the PWM frequency and to check that there is no refraction phenomenon on very long power supply cables (high voltage peaks and dv/dt).

thermal protection

It is realized through a normally closed contact heat protector with the following characteristics:

Operating temperature 135± 5°C
Max. voltage 48 Vdc, 230 Vac
Capacity of the contacts 6 Adc, 6 Aac (cosϕ=0.6)

Alternatively it is possible to foresee the following types of sensors:

  • thermistor PTC type SNM130ES520
  • PT100 type 41SRPE06
  • KTY84-130

 

options
  • Cooling: the motor can be supplied in closed not ventilated version TENV (IC400 according to CEI EN60034-6) and with liquid-cooling TEWC (IC3W7 according to CEI EN60034-6). On request it is available a cooling system with external ventilation that does not need an hydraulic circuit but allows to achieve a good ratio dimensions/torque.
  • Position transducer: the motor can be supplied with different types of encoder in accordante with customer’s requirement. The encoder assembling can be coaxial, in case of standard or hollow axle shaft motors or coupled through belt in case of hollow shaft motors.
  • Brake: the motor complete with holding/emergency brake is available on request.
  • Oil seal: on request the motor can be supplied with Angus-ring oil.
  • Connections: standard set up involves a terminal board for the power and connector for the transducer. On request it is possible to supply free cables 1 m long or connectors (always supplied complete of male and mating).
  • Coupling: the motor can be equipped with different types of shaft end according to the request and the application:
    • shaft with or without keyway
    • hollow shaft
    • blind hole shaft
    • shaft with external gear teeth
    • hollow shaft with internal gear teeth

    The motor can be supplied as rotor-stator, therefore with no bearings and suitable to be integrated to the machine. In the complete version different types of bearings can be provided according to the application:

    • balls - balls
    • balls - rollers

    In extruder applications it is possible to use reinforced bearings.

  • Protections: normally in IP54, on request IP65.
  • Painting: preliminary painting for external surface with epoxy bicomponent primer is foreseen, suitable for any type of finishing enamel. Special paint finishes can be provided on request.
parameters

The values indicated on the tables correspond to what follows:

  • Stall torque Tn0: continuous torque that can be supplied by the motor while running at a speed near zero with ΔTmax=105K (max room T=40°C)
  • Max torque Tp: acceleration torque that can be supplied by the motor
  • Max speed nmax: max speed when the load is equal to the stall torque Tn1 and the voltage supplied to the motor is equal to the max voltage that can be delivered by the drive (Vac)
  • Area 1: since an increase in speed results in bigger losses of the motor, it is necessary to derate the continuous torque (S1 IEC34-1) according to the speed as shown in the graph
  • Area 2: when choosing the motor it is necessary to take into account the speed up to which the max torque has to be supplied; this depends on the max voltage which can be delivered by the converter.
