Stepping motor

The stepper motors are substantially synchronous motors without brushes constructively made to transform, by means of the control electronics, control pulses into precise movements (steps) mechanical, with extreme simplicity of use, for the majority of cases open loop.

Typically, it is referred to 2-phase stepper motors (200 steps per revolution) and 5 stages (500 steps per revolution).
Used in applications where one wants to exploit greater torque at low speed, it doesn’t require the control position with the engine stopped because perfectly blocked by the very nature of the construction of the engine.

A) 2 phases Stepper Motors in the standard version (torques up to 20 Nm) and high performance version (high torque and efficiency, lower noise and vibrations, torques up to 25 Nm).
Control electronics consisting of bipolar chopper drives, DC power and AC, card versions, box and rach.
Power up to 240 VDC, 14 A / phase max.
Operating from 200 to 4,000 steps / rev (microstepping).

B) 5 phases Stepper drives motors, with torques up to 37 Nm (version with reducer)
Powers 24-36 VDC and 200-300 VAC single phase.
Combination with several standard types of gearboxes, also in “harmonic”

C) Stepper systems “closed loop control” with position sensor on the rotor, used to prevent the loss of synchronism in the motor movement.
Torques up to 37 Nm in the version with reducer “harmonic”
24VDC and 200-230 VAC single phase
Operating from 500 to 10,000 steps / rev.
