Product Description:

Pacific Scientific offers precision automation solutions for motion control systems. The product R33HMNP-R2-NS-VS-00 R Servomotor. The R Servomotors are designed for environments demanding performance and mechanical integrity. This model belongs to the R33 series and is designed for reliable industrial use. It features a rare earth magnet type using samarium cobalt for optimal performance.

The R33HMNP-R2-NS-VS-00 R Servomotor has a width of 3 inch which matches its magnet stack length of 3 inch. The product has a compact form and provides stable output for continuous operations. The R Servomotors with are built with a winding code H configuration. It comes with a metric shaft and mounting for standardized integration. The motor does not include a holding brake and supports primary feedback only. It uses a frameless resolver of transmitter type with size 21 for primary feedback. There is no secondary feedback supported in this model. The shaft sealing is done using durable Viton material to ensure reliable operation. The unit provides a continuous stall torque of 2.5 Nm. Its maximum torque output is rated at 6.54 Nm. The inertia is measured at 0.093 x 10^-3 kgm^2 which confirms smooth rotation. The static friction for the motor is maintained at 0.04 Nm for precise motion and viscous damping coefficient is marked at 0.007 Nm/KRPM which helps control speed.

The R33HMNP-R2-NS-VS-00 R Servomotor has a thermal resistance value of 0.84 deg. C/Watt to support heat management. Its thermal time constant is defined as 23 min for controlled temperature rise. The total mass of the unit is 3.2 Kg which supports its compact design. The R33HMNP-R2-NS-VS-00 motor is suitable for operations requiring consistent torque and feedback.
