Product Description:
The PMB31D-20214-01 is a synchronous motor in the Pacific Scientific PMB product series. This motor provides excellent reliability in applications that require precise and dynamic motion. Its small size and low inertia engineering ensure seamless performance in tasks that require quick speed changes and rapid responses to control commands. The motor comes equipped with a digital encoder with integrated commutation, providing precise feedback on rotor position, speed and direction. This built-in feedback enables the controller to precisely align current phases, resulting in smooth delivery of torque and high precision in motion control.
The PMB31D-20214-01's continuous stall torque of 2.1 Nm is the most torque the motor can produce without overheating when it is stationary. This allows the motor to consistently sustain a load or withstand external forces when it is not in motion. The motor is engineered to operate at a continuous rotational speed of 5000 RPM, ensuring fast speeds for high-speed motion control processes. This speed capability allows the motor to support both moderate and fast cycles times across automation environments, providing versatile functionality to suit a wide range of automation demands. This motor comes with a square key shaft design that is optimized for effective torque transfer without slippage. The square key shaft improves motion accuracy and lessens wear on the motor, contributing to low-maintenance operation and overall durability.
The electrical interface of the PMB31D-20214-01 utilizes MS (military standard) connectors, which offer safe, vibration-resistant connections. These connectors lower the chance of signal loss or disconnection by ensuring dependable electrical contact even in challenging industrial settings. This motor has a mass of 5.2 kg weight that ensures mechanical stability while in use, without adding significant bulk to existing setups.
