Product Description:
The R46HMNA-R2-NS-NV-00 Servomotor of Pacific Scientific features a standard build, reliable primary resolver feedback and robust IP65-rated protection which makes it ideal for precision applications in controlled industrial environments.
The R46HMNA-R2-NS-NV-00 produces back EMF of 0.61 volts per radian per second when it turns and it uses a frameless resolver as its main position-sensing mechanism which is electromagnetic and operates without a housing and follows the transmitter format which means it outputs a sinusoidal signal that correlates with shaft position. To block dust, moisture or fluids it has no additional protective barrier which may reduce friction or cost but could be a limitation in environments where contaminants are present. It has a 10 inches long magnetic core inside the rotor which directly influences the electromagnetic strength and, in turn, affects how much force the motor can deliver and it belongs to the R46 classification which identifies its general mechanical and electrical design profile. The moment of inertia given in kilograms meter squared is 0.00038 which quantifies the resistance of the motor rotor to changes in its rotational speed and it is constructed with winding configuration H, which defines how the copper wire is laid out inside the stator.
This R46HMNA-R2-NS-NV-00 Servomotor does not have a built-in mechanism to lock or hold the shaft in place and all of its mechanical mounting and shaft dimensions conform to the metric system which makes it compatible with internationally standardized machinery and components that use millimeter-based fittings and fasteners. It requires 106 amps of electric current to deliver its maximum mechanical output and it is able to rotate 30.5 Newton-meters of load at its strongest performance point.
Frequently Asked Questions about R46HMNA-R2-NS-NV-00:
Q: Why does the R46HMNA-R2-NS-NV-00 use a frameless resolver instead of a housed encoder?
A: The frameless resolver allows for compact integration in tight spaces. It also offers excellent durability and noise immunity in high-vibration environments.
Q: How does the 0.61 V/rad/sec voltage constant affect servo drive selection?
A: This constant determines the voltage required per speed unit. Matching the servo drive’s voltage range ensures efficient motor control and response.
Q: What’s the advantage of using winding H in the R46HMNA-R2-NS-NV-00 servomotor?
A: Winding H offers a balance between thermal performance and torque output. It also optimizes electrical characteristics for precise motion control.
Q: Why is a frameless resolver preferred in high-speed feedback systems?
A: It provides continuous position data without mechanical wear. This ensures long-term reliability and stable signal output at high rotational speeds.
Q: How does the 10" magnet stack in the R46HMNA-R2-NS-NV-00 impact torque delivery?
A: A longer magnet stack increases the magnetic field interaction, producing greater torque. It also supports higher load applications without sacrificing responsiveness.
