Product Description:

Pacific Scientific's S33GMNA-RNNM-00 stepper motor is made to offer precise motion control for a wide range of applications. Its consistent performance is guaranteed by its strong feedback mechanisms and compact and robust design. It is optimal for industrial automation applications that necessitate precision and dependability.

The S33GMNA-RNNM-00 stepper motor has a NEMA 34 frame size and a 3-stack length. It can produce up to 14.8 Nm of power. With a constant standstill torque of 5.1 Nm, it ensures steady operation even when it is under load. It is easy to change speeds with a viscous damping value of 0.047 Nm/Krpm, which makes the motor work better. It has an inertia of 0.46 x 10-3 kgm², which helps the motor be controlled accurately. This motor is perfect for places with limited room because it only weighs 6.5 kg. It has a thermal time constant of 27 minutes and a thermal resistance of 0.87 Celsius/Watt, which ensures that it manages heat well and works efficiently while it is running. For exact feedback, the motor has a 21-sized frameless resolver that gives correct position information. The design stays simple and streamlined because it does not have a secondary input system. This makes it reliable and easy to use in a wide range of industrial and business settings.

The S33GMNA-RNNM-00 stepper motor motor-mounted MS link that makes terminations easy and has 0.170 Nm of static friction. A holding brake is not available on this motor. Due to its wide constant torque range (0.5 to 6.6 Nm), it can be used in many different situations. The motor guarantees reliable performance with its small size and effective torque control. The motor is perfect for systems that need to be very precise and reliable.
