Product Description:

The PMB32D-00200-03 is a brushless servomotor produced by Pacific Scientific and supplied in the PMB Brushless Servomotors series. Designed for closed-loop motion axes in industrial automation, the motor integrates with digital drives to provide repeatable torque and position control without mechanical commutators. Its electromagnetic design supports consistent speed regulation for pick-and-place units, small gantry systems, and indexing fixtures where dynamic response and durability are important. Because it relies on permanent-magnet excitation, the unit reduces the maintenance associated with traditional brushed designs while sustaining high torque density for compact equipment layouts.

The frame conforms to the NEMA Size 34 envelope, allowing direct installation in standard 3.4-inch square mounts. Under a 240 VAC bus, the nominal stall current is limited to 5.4 ARMS, so drive electronics can be sized for moderate continuous current while still accommodating dynamic peaks. Power and feedback are delivered through flying leads with MS connectors, simplifying field wiring because the mating receptacles are already crimped to the pigtails. Rotor position is reported by a resolver, which supplies analog sine-cosine feedback that withstands electrical noise and high temperatures better than many digital encoders. Environmental protection includes a shaft seal and PTC thermistor; the seal helps retain lubricant inside the housing, and the thermistor supports thermal shutdown before winding insulation is overstressed.

A flat machined section on the output shaft provides a simple drive-hub interface when keys are undesirable or space is restricted. The motor uses a stack length multiple of 2, which balances inertia and torque so acceleration remains responsive without making servo tuning unnecessarily difficult. This combination supports compact motion systems that need steady coupling behavior and reliable thermal protection during repeated starts, stops, and indexing cycles.
