2-фазные шаговые двигатели / приводы Tamagawa AU9118N1

Описание

• Capable of controlling precise position in open loop
  • Rotational angle is proportional to the number of input pulses.
  • Rotational speed is proportional to the input pulse rate (pulse frequency).
  • Angle error (Positioning error) is very small and is not accumulated.
• Capable of holding the static position stable by self-holding torque
  • Biggest self-holding torque (Holding torque) is generated in the state of exciting the motor windings.
  • Even in the state of non-exciting, some self-holding torque (Detent torque) is generated because the permanent magnet is used.
• Capable of responding fast to the starting, stopping and reversing with its superior acceleration
• No maintenance is needed for the mechanical wear as is often the case with brushes for DC motors
• Merit of 5-Phase Step motors
  5-phase step motors have the superior characteristics of resolution, vibration, performance and others compared with 2-phase step motors.
• High resolution
  0.72° for full step and 0.36° for half step. These are the resolution of 2.5 times compared with 2-phase step motors.
• Low vibration and smooth rotation, because the torque ripple is small and the variation of operating torque is extremely small.
• Fast response
  The out of synchronization caused by resonance is rare in the range of low and middle rotational speed unlike the conventional 2-phase step motor, and it is capable of controlling the fast positioning by means of slow-up and slow-down the step resolution is 2.5 times as accurate as the conventional step motors.
