Product Description:

Pacific Scientific's 33VM62-220-3 servo motor is made to respond very quickly to movement commands. A high-torque-constant winding, an optical encoder, and an analog speedometer are some of the high-tech features built into this motor. It gives exact control that works well in many situations, like industrial automation, where fast and accurate movements are needed.

The 33VM62-220-3 servo motor can handle 6.7 Amps RMS at 24 V and 5.7 oz-in/Amp of power, so it can keep working well even when it is under a lot of stress. It has a motor inertia of 0.0052 oz-in-sec², which means it can quickly speed up and slow down, reducing reaction times. It comes with a traditional tachometer that measures voltage with a slope of 2.5 V/kRPM and a voltage ripple of no more than 1.5 V from peak to peak. The tachometer provides a dependable input system that makes sure the speed control is correct. The motor's end resistance is 0.85 ohms, which means that it loses very little energy. The design has air intake and exit baffles to make cooling better. The motor's shaft is physically connected to a precision blade system. This makes the mechanical connection reliable in situations that need to be precise.

The 33VM62-220-3 servo motor also has built-in connections that make installation easy. The optical encoder gives accurate position input, which improves performance. The motor's air mesh grills help get rid of heat when it is running all the time. Power management is easy because it has a DC control system built in. The motor is small and efficient, so it can be used in many situations that need high-speed and accurate control.
