Product Description:

The 33VM62-000-21 is a permanent magnet direct current motor built by Pacific Scientific to provide ultra-fast positioning and low inertia during operation. This unique design of the motor rotor allows it to move connected loads through extremely fast start-stop sequences while maintaining a high degree of precision. The motor unit also features a low inductance level, which allows it to produce smoother torque and a faster motor response. Compared to other industrial motor series, this product has a significantly smaller size that can fit into the tightest space. The 33VM62-000-21 employs the use of Alnico V-7 magnetic material for its excitation; however, it is without a tachometer or optical encoder unit. There is no air blower installed inside this servo motor unit, which allows it to maintain a quieter operation in the automation system.

The 33VM62-000-21 uses special carbon-brushes for its commutation. These brushes are particularly desirable for their ability to maintain optimum operation for long periods. The typical service life of the brushes is about 5000 hours; however, they can be easily removed and replaced once this time is exhausted. The rotor of this industrial motor has a small diameter, and it is also provided with reliable protection that meets at least the IP65 category. The thermal resistance of this industrial motor is estimated to be about 1.29 ohms; its rated input current requirement during operation is also about 30 amperes. During the rated operation of this product, it can deliver a rated torque of about 5.4 newton meters.

The 33VM62-000-21 motor is delivered in a recyclable cardboard box. Wake Industrial offers customers worldwide delivery through FedEx, UPS and DHL. There is also a warranty period of 12 months offered to customers who purchase the motor from our store.
