Speed-torque curve

• Instantaneous maximum torque line
  The maximum torque momentarily impacts the load when the motor is started.
  Beyond this torque, the over-current protection of the driver will cause the motor to stop.
• Short time operation area
  The motor can run at a short time within this torque range at different speeds.
  If the operation time is too long, the motor will generate heat, which may cause the motor to stop or burn.
• Rated operating torque line
  The rated torque of motor running at different speeds, and the motor can run for a long time at this torque.
• Continuous operating area
  When the motor rotates at different speeds, it runs continuously in this corresponding zone.

Tips: Causes of planetary gear motor noise

• When using a planetary reducer, noise may sometimes be generated. In this way, many people who don't understand planetary reducer will think that there is a problem with the planetary reducer and dare not use it. In fact, the noise produced by the planetary reducer is caused by many factors.
• The rotation of the motor bearing produces natural sound under normal circumstances, and there is almost no problem except for the case of a precision miniature motor or a geared motor. However, the natural vibration of the bearing and the resonance of the material of the motor components, and the gas spring constant of the bearing axially cause the rotor to vibrate axially, and poor lubrication produces frictional noise.
• When the brushes slide, DC motors or commutator motors with brushes will generate brush noise.
• The fluid noise and ventilation noise generated by the fan or rotor are unavoidable. In many cases, the overall noise of the micromotor will be affected. In addition to the air whistle sound caused by fan blades or iron core teeth, pay attention to the resonance of ventilation.
• Electromagnetic noise refers to the noise caused by the unbalance of the magnetic circuit or the unbalance of the magnetic force of the air gap and the electromagnetic wave, and the magnetic noise caused by the saturation of the magnetic flux density or the eccentricity of the air gap.
• Mechanical vibration noise is the unbalanced weight of the rotor, which produces a considerable number of rotations.
