Product Description:

The PMB33F-20216-01 is a motor unit engineered for reliable operation. It comes with balanced mass, control, and heat stability. At a rotor inertia of 0.404 kg·m² x10⁻³ when equipped with a resolver, it offers smooth acceleration and deceleration and helps to reduce mechanical shock during directional motion.

Its function helps to deliver precise movement in systems that require stringent starts and stops. The motor peaks with a maximum length of 210.3 mm (8.28 inches), making it easy to integrate into equipment with moderate space requirements. Its compact design helps to maintain design flexibility without compromising power output. At a weight of 6.3 kg (13.8 pounds), it gives a heavy-duty mass-to-power ratio. It has enough torque and is easy to mount and service. This has a cable bend radius of 57.2 millimeters or 2.25 inches. It gives wiring that can stay intact in assembly or motion. It has maintained signal integrity and no premature cable wear. This comes with a thermal time constant of 32 minutes. It can absorb and dissipate heat slowly with time. The long thermal response will help it to operate under varying loads. It will work without overheating. Also, it is crucial for cyclical operations. In addition, the thermal resistance of 0.78 °C/Watt expresses efficient heat transfer from windings to the motor housing, with temperature management during long-running. This combination of thermal properties helps to maintain internal component longevity and allows continuous-duty running. The PMB33F-20216-01 is ideal for running in applications with moderate inertia requirements and long operating cycles.

Whether integrated into inspection platforms, coordinated assemblies, or rotating equipment, the motor delivers mechanical stability, controlled motion, and thermal reliability. Its physical construction and performance properties allow for consistent performance in automated systems that demand responsiveness along with consistent thermal performance over the long term.
