Product Description:
The PBM423DGBC21 Stepping Motor of Sanyo Denki with an integrated low backlash gear head is designed for precise and high performance industrial automation applications. This product is listed in the PB SANMOTION Servo Motors series.
The PBM423DGBC21 stepper motor length is 3 inches which provides a sense of its size and the size of its frame is 42 mm in diameter. The amount of mechanical slack or play in the gear system of the motor is 0.25 deg or less which means minimal delay or movement when the direction of the motor is changed. It is powered by direct current and its multi axis feature means it is typically used in systems with multiple motors that require synchronized movement. Its optical incremental type of encoder generates pulses of 800 P/R as the motor shaft rotates that allows the controller to track its position. The module uses a gear system with low backlash, which means the gears have minimal play or lost motion which ensures that the motor provides precise and repeatable movement. It functions on a two-phase system in discrete steps as each phase is energized in a sequence which is typical for stepping motors.
The PBM423DGBC21 stepper motor communicates with a controller via RS-485+Parallel I/O+Pulse train interface, such as RS-485 is a standard for serial communication over long distances, while Parallel I/O is used for transferring multiple bits of data simultaneously. It has a D shaped output shaft which is designed to fit into matching D-shaped holes or couplings to prevent slipping. It has 250 revolutions per minute (RPM) of allowable speed and exceeding this limit may damage it or reduce its efficiency.
Frequently Asked Questions about PBM423DGBC21:
Q: Why is the PBM423DGBC21 Stepping Motor’s encoder resolution important?
A: The 800 P/R encoder resolution allows for precise positioning and smoother operation. This high resolution improves accuracy in multi-axis applications.
Q: How does the low-backlash feature of the PBM423DGBC21 benefit performance?
A: The low-backlash gear system minimizes positional errors and provides precise, repeatable movements. This feature is essential for applications requiring high accuracy.
Q: What is the role of the D-shaped output shaft in PBM423DGBC21?
A: The D-shaped output shaft ensures a secure connection with mechanical components. It prevents slippage during motor operation, improving the overall reliability of the system.
Q: How does the PBM423DGBC21 handle multiple-axis synchronization?
A: The DC power supply and multi-axis feature allow multiple motors to operate in sync. This is critical in systems like robotics and CNC machines.
Q: What are the benefits of the PBM423DGBC21's RS-485 communication interface?
A: RS-485 allows for long-distance communication with minimal signal loss. It’s ideal for environments where multiple motors are distributed over larger areas.
