Product Description:
The model PMB32D-00200-03 is a compact high torque brushless servo motor. It offers stable performance and precise control for automation and motion control tasks. It fits well into mid sized applications with a NEMA 34 frame size.
This PMB32D-00200-03 servo motor has a continuous stall current rating of 5.2 A which defines the maximum current it can sustain indefinitely at stall without overheating or exceeding its thermal limits. The torque constant of the motor is 0.74 Nm/A. It features a flat shaft for secure mechanical coupling and includes a shaft seal for environmental protection. The resolver sensor enables reliable position feedback. The voltage constant (line to neutral) is 0.46 V_RMS/rad/sec that supports smooth speed regulation. The motor dissipates heat effectively under prolonged use with a thermal resistance of 0.92 °C/W. The static friction of this servo motor is limited to a maximum of 0.12 Nm that aids in smooth motion starts. The servo motor also supports a peak current rating of 15.6 A that allows it to deliver short bursts of high torque during transient or demanding load conditions. Its mechanical inertia is measured at 0.27 ×10⁻³ kg·m². This offers responsive acceleration and deceleration. The motor comes equipped with flying leads and MS connectors for versatile installation and secure connectivity.
The PMB32D-00200-03 servo motor has a weight of 4.4 kg that is suitable for integrated systems without adding excess bulk. The motor's NEMA 34 frame ensures compatibility with a wide range of mounts and accessories. This PMB series servo motor is optimized for use with a 240 V AC supply and a 320 V DC bus that is compatible with standard industrial drives and power systems.
