PMB31D-10200-03

Product Description:

The PMB31D-10200-03 brushless servomotor stands as a workhorse in the world of automation, produced by Pacific Scientific for the PMB Brushless Servomotors series. The case measures out to about 134mm x 40mm x 30mm and lands at around 350 g in weight, making it manageable when space or mounting flexibility matter. Power output is one of the stronger points: 100 A is the current rating, which goes together with a 1200 V voltage rating. The voltage clearance doesn’t just stop at the standard rating either—there’s 2500 Vrms isolation voltage for added safety margins when conditions get rough.

This servomotor uses IGBT die technology on the inside, helping keep switching fast and losses low. A mounting style with screw fittings gets it fixed to place with minimal fuss, even in tougher setups where hardware can shake loose. Heat and moisture don’t slow it down much either, with operation approved from -40°C to 150°C, which means electrical cabinets, lines by ovens, or even cooler zones aren’t off-limits. The motor counts on logic level inputs, so dialing in settings or wiring to a drive doesn’t have layers of complication. The collector-emitter saturation voltage (1.8 V typical) helps keep switching temperatures from spiking, especially during active cycles.

Applications usually see this model dropped into heavy industrial backs—the ones driving robotics arms, conveyor lines, or presses wanting repeatable moves every shift. Keywords for use: “Industrial Automation” and “Reliable Operation,” because a motor that quietly handles vibration and voltage jumps means less stoppage down the line. Isolation voltage at 2500 Vrms keeps sudden surges from frying things. Feedback isn’t fancy but direct, so it corners well when used for cycle timing. This part tucks in, bolts down, and just grinds out steady performance shift after shift—fewer headaches, easy replacement, and rarely any drama during maintenance checks.
