PMB33C-00114-02

Product Description:

The PMB33C-00114-02 servomotor from Pacific Scientific slips into the PMB Brushless Servomotors line – a spot where compact size and solid torque matter. This model arrives inside a NEMA Size 34 frame with an exterior that keeps everything neat and won’t crowd crowded control panels. Its rated speed of 1,900 RPM works fine for steady positioning jobs or running cycles that ask for consistent, repeatable movement. Maximum force comes in at 16.1 Nm peak torque, which covers bigger starts or stops that sometimes pop up in automation work. The housing sits under an IP40 rating, designed mostly for dry, indoor gear, but still helping to keep out small bits of dust.

Wiring connects through flying leads with AMP connectors, giving some flexibility for setups that move or need direct line runs. Along the shaft, commutation sensors keep the sequence tight, and the digital encoder comes standard for close control. For jobs needing exact position feedback every round, the 2048 ppr encoder resolution sits in that sweet spot, making alignment jobs a little less of a hassle. When the work keeps up for long stretches, continuous stall torque sits at 5.42 Nm, holding steady without needing constant resets. Inside, the 3.8 ARMS nominal stall current at 240vac keeps things efficient, while the weight comes in at 6.3 kg, so installs and swaps don’t involve heavy lifting.

The structure inside pulls power smooth, thanks to 1.4 Ω line-to-line resistance and 20.4 mH inductance, giving it good control over startups and shifts. Stacking hits a 3 on length, keeping the profile in bounds for most out-of-the-way cabinet installs. The 8.9 A RMS peak current means sudden jolts don’t throw things off-kilter. Rotor inertia at 0.404 kg·m² ×10⁻³ helps keep movement crisp even when loads change.
