Saia Motors Important notes

General
All specifications for torque, force and power are representative only and maybe subject to variation due to manufacturing tolerances.

Saia motors motors, except UR types, fulfil basis insulation requirements of EN 60335-1: 2004.

Application advice
The requirements for protection class I, II or III according to EN 60355-1: 2004 have to be fulfilled by customer application.

Stepper motors
Specified data for torque values is valid for

  • a duty cycle of 100%, in Performance Charts additionally for 30% (cycle time: 5 min, type URG only 1 min.)
  • an ambient temperature of 23 ±5°C
  • a defined driver circuitry, with constant
    voltage supply
  • at rated voltage

If duty cycle or actual maximum ambient temperature is lower, the motor can be designed for higher performance (torque and power) by using a different winding.Chopper driver circuits can be applied alternatively to a driver with constant voltage supply. hey are more expensive, but bring higher performance. Additionally, they eliminate the effects of temperature and supply voltage change. Performance charts available on request.Step angle tolerance is about ±5% (not cumulative).

Synchronous motors
Specified data for torque/power values are

  • a duty cycle of 100%
  • an ambient temperature of 23 ±5°C
  • at rated voltage
  • synchronous torque (not starting torque)

Torque is specified with maximum values, overloading is not permissible.

If duty cycle or actual maximum ambient temperature is lower, the motor can be designed with higher performance by using a different winding.

The basic design is the same as for our stepper motors, but the motors are operated by a sinus waveform voltage.
A capacitor, connected to one of the motor coils, is necessary for rotation in the appropriate direction.

Motor type UDS is a special design: It has only one coil, but is fitted with an internal ratchet. This ratchet determines the direction of rotation. A capacitor is not necessary.

Mechanical and electrical connections
On request we can deliver other options, e. g.

  • special motor shafts
  • pinions on shaft
  • special cable lengths
  • connectors
