Vectorial Induction motors for spindle, MA series
Special induction motors,with reduced dimensions, suited for variable-speed applications with vectorial inverter with flux control. The specially accurate mechanics and the original electro-magnetic design allow speeds up to 9000 rpm.
The case cooling with separate fan allows reduced dimensions and high continuous torque even at low speeds.
The MA series comes in 5 sizes:
with powers from 3 to 100Kw.
Base speeds are 750, 1000 and 1500rpm (750rpm units are availanle star/delta connected)
When the S1 power is over 40Kw the windings are for 400Vac 3-phased: in this case a 625Vdc bus is necessary (as it is generated by D.Electron regenerative power supplies).
Windings are specially coated for high electrical insulation, necessary for inverter drives.
Motor MA225: finite element design - Stator - Rotor
Integrated position transducers
- Incremental encoder sincos 1Vpp 2048 pulses/turn (standard)
- Incremental encoder Line Driver TTL,1024 pulses/turn
- Bipolar Resolver
The probe KTY84-130 is casted in the stator windings (the D.Electron Z-Star2 digital drive system monitors the motor temperature during operations)
The standard execution has a terminal block for power and a connector for transducer and fan. In the standard execution the terminal-block box is in the upper side, connections toward left by observing from the shaft output side. D.Electron may supply cables conform to the most severe environmental conditions
Optional on any size
The standard is B3; optionally all the solutions conform to the IEC34-7 are available
