Product Description:
The 2VM62-004-4 is a permanent-magnet DC servomotor from Pacific Scientific in the Low Inertia PMDC Servomotors series. Designed for closed-loop speed and position control, it provides quick torque rise for pick-and-place modules, light conveyors, and other small industrial axes. By coupling with an external drive and feedback device, the motor delivers the fast response needed to keep throughput high while maintaining repeatable motion profiles in automated equipment. Its armature and lightweight rotor minimize moment of inertia, helping machines shorten cycle times.
Physical size supports tight panel layouts: the cylindrical body measures 2.700 in in diameter and overall length is 4.042 in, so the motor fits into confined assemblies. Despite the compact envelope, it weighs only 2.75 lb, easing integration on sliding carriages. Heat generated during operation is limited to 54 W of power dissipation, and this load is transferred to ambient air through conduction because the design specifies no forced-air cooling. A thermal resistance of 2.41 °C/W describes how rapidly the frame climbs in temperature under continuous current. Alnico V-7 magnets supply the flux path, and the 2.450-inch mounting bolt circle lines up with standard NEMA 23 mounting plates for direct installation on common fixtures.
The output shaft is intended for direct coupling to gears or pulleys; its diameter is 0.249 in with a keyed engagement length of 1.378 in to support moderate overhung loads. Position information is provided by a square dual-channel optical encoder that uses an LED light source and operates from a regulated 5 Vdc ±5% supply at up to 150 mA. Because the encoder omits a zero index, homing routines must reference an external sensor. No analog tachometer is installed, so speed feedback is strictly digital. Static friction torque is 1.8 oz-in, giving predictable breakaway characteristics for precision stall-holding applications.
