Product Description:
The PMB33F-00214-03 is a brushless servomotor which is a NEMA Size 34 frame unit developed by Pacific Scientific. It has a digital encoder with commutation built in, which gives 2048 pulses per revolution for accurate motion control. The motor is designed to be used in industrial robotics, which needs to be accurate and dependable.
The PMB33F-00214-03 brushless servo motor can produce a continuous stall torque of 5.4 Nm and a high stall torque of 15.9 Nm. The rated torque is 4.4 Nm, and the peak rated torque of 15.9 Nm is the same as the peak stall torque. Speed at no load is 4,500 rpm, and speed at full load is 3,500 rpm. A steady stall current of 4.6 A RMS is required, and the current must be 9.1 A RMS when the torque is at its peak. As a result of the motor's inertia value of 0.27 x 10⁻³ kg·m², the rates of acceleration and braking are maintained in a consistent manner. There is a steady flow of power since the inductance between the lines is 4.4 mH, which indicates that the lines are connected.
The PMB33F-00214-03 brushless servo motor has a connector design that uses flying leads and MS connectors to make sure interactions are safe while the device is working. The motor has a flat shaft, which makes it easier to connect to mechanical devices. The configuration gives correct torque delivery and stable speed control. The motor can work well in servo applications. The servo motor is made to work with standards for industrial automation. The motor helps the system work reliably and efficiently.
Frequently Asked Questions about PMB33F-00214-03:
Q: Why does PMB33F-00214-03 include a continuous stall current of 4.6 A?
A: The continuous stall current of 4.6 A ensures the motor sustains torque without overheating. It allows stable performance during extended duty cycles under demanding mechanical loads.
Q: Does PMB33F-00214-03 benefit from 0.27 kg·m² x 10⁻³ inertia?
A: The low rotor inertia value of 0.27 x 10⁻³ kg·m² enables fast dynamic response. It supports precise acceleration and deceleration during servo operations.
Q: Why does PMB33F-00214-03 have a no-load speed of 4,500 rpm?
A: The no-load speed of 4,500 rpm demonstrates the motor’s maximum rotation capability. It provides a margin above rated speed for flexible control across varying loads.
Q: Do the flying leads in PMB33F-00214-03 provide integration advantages?
A: The flying leads with MS connectors provide simplified electrical integration. They ensure secure connections that maintain electrical reliability and reduce installation complexity in servo systems.
Q: How does PMB33F-00214-03 use the inductance line-to-line of 4.4 mH?
A: The inductance line-to-line of 4.4 mH smooths current flow between phases. It improves torque consistency and reduces electrical noise during continuous motor operation.
