Product Description:

The 2VM62-030-11 is a low-inertia permanent-magnet DC servomotor produced by Pacific Scientific within the Low Inertia PMDC Servomotors series. It converts armature current into torque for positioning and velocity regulation tasks in industrial automation, where rapid acceleration and precise speed control are required. Its low-inertia rotor supports quick response during start-stop cycles. The motor is suited for compact motion axes that depend on repeatable torque at changing speeds.

During continuous operation the motor dissipates 59 W of copper and iron losses across its external surface. With no forced-air cooling, the allowable heat rise is set by a thermal resistance of 2.41 °C/W, so enclosure temperature tracks load directly. These thermal figures affect enclosure temperature during sustained loads. An intermittent torque limit of 5x rated allows short bursts of acceleration without structural damage, while static friction torque remains 1.8 oz-in maximum, allowing small command inputs to overcome stiction. Magnetic flux is developed by Alnico V-7 permanent magnets, stabilizing torque production over a wide temperature band. Speed feedback is supplied by an integral through-shaft analog tachometer, and there is no optical encoder attached, leaving the rear face open for user-selected feedback devices.

The mechanical envelope is compact: the cylindrical body measures 3.5 in long and 2.7 in in diameter, yet weighs only 2.75 lb, easing integration on lightweight axes. A 0.249 in diameter shaft provides the drive interface, while the overall length, including the tachometer housing, reaches 5.429 in. Installation is through a four-hole pattern on a 2.450 in bolt circle threaded 6-32 UNC-2B, matching common servo gearheads. These physical parameters support use in pick-and-place heads, indexing tables, and other axes that benefit from low moving mass and high acceleration capability.
