Product Description:
The Pacific Scientific 2VM62-024-4 is a permanent-magnet DC servomotor in the Low Inertia PMDC Servomotors series. Designed for positioning axes that must accelerate quickly with limited reflected inertia, the unit converts direct-current power into controlled torque for pick-and-place stations, light gantries, and other industrial automation tasks that demand rapid reversal. Pacific Scientific integrates the rotor, magnet set, encoder, and tachometer in a single frame so the motor can be coupled directly to servo controllers without external transducers.
The motor uses no forced-air cooling, so heat is removed by conduction through its mounting surface. Feedback is supplied by a dual-channel optical encoder; the light source draws 150 mA, and its flutter remains below 1.0% p-p, supporting velocity stability. Quadrature tracks deliver incremental position data, and the assembly omits a zero index, simplifying wiring when an absolute marker is unnecessary. Encoder illumination is produced by an LED, and its square signals are conditioned internally before reaching the drive. The encoder operates without a reference channel to minimize component count while still providing two-phase resolution.
The incremental outputs arrive at the controller as square-wave pulses referenced to a regulated 5 VDC ±5% supply. Magnetic flux is supplied by an Alnico V-7 ring that resists demagnetization during repeated reversals. For velocity feedback, the standard analog tachometer maintains ±0.5% linearity, produces 1.5% p-p ripple at most, and has 50 ohms of armature resistance. Its rotor inertia is only 0.00005 oz-in-s², matching the motor's low-inertia profile. The tach generator delivers 2.5 V/kRPM, letting the servo amplifier derive gain proportional to shaft speed. With both encoder and tachometer housed inside the same frame, digital or analog control loops can be used without additional external hardware.
