Stepper motor low speed and high torque equipment makes transmission shorter, which means higher reliability, higher efficiency, smaller gaps and lower cost. It is this characteristic that makes the robot ideal for stepping, because most robot movements are short-cycle cycles that require high acceleration to reach a low point. The power-to-weight ratio is lower than that of a DC motor. Yamasha Electric believes that most robot movements are high speed (and therefore high power) over long distances, but usually include short distance stops and starts. They are ideal robots at low rpm and high torque. All ST robots have encoder feedback which is relative to the software motor count. In the case where no errors can be corrected, the system will stop. Therefore, the integrity of the system is much higher.
So the advantages of using stepper motors in robot design are as follows: 1 is cheaper for stepper motors of equivalent performance. 2 Stepper motors are brushless motors and so have longer life. 3 as a digital motor can accurately locate without hunting or overshoot. The 4 driver module is not a linear amplifier, which means fewer heat sinks, higher efficiency, and higher reliability. The 5 driver module is cheaper than a linear amplifier. The 6 does not have expensive servo-controlled electronics because the signal originates directly from the MPU. 7 Software fail-safe. Main control board problem step pulse. If the software does not work or crashes the motor stops. 8 electronic drive fail-safe. If the motor locked by the drive amplifier fails, it will not run. When the servo drive fails, the motor can still run and may run at full speed. 9 speed control and repeatable (crystal control). 10 If required, stepper motors run extremely slowly. Stepping motor positioning device, so there can be no wrong work, such as not slow down under excessive load, but it will stop. They cannot be used to exert the forces of independent positions. But the robot is a positional device designed to enter the position without errors. A robot whose watchdog encoder reports an error and stops further actions during first gear or collision.
In some low-speed stepper motors, the loss Air conditioning fan motor suppliers of resonance synchronization and procrastination can be generated. Each stepper motor driver is controlled by an independent microprocessor. The pseudo-sine of the drive motor is called a microstep. The microcode watch resonates and automatically switches the phase and current to compensate. In micro-stepping mode running on a silent drive, the motor can be seen in the video over the entire speed range.
