Product Description

The M22NRFB-LDN-NS-00 is a DC Stepper Motor originally manufactured by Pacific Scientific and now available from Pacific Scientific. This motor is designed to operate at 65 VDC supply voltage and it is a bipolar design. The M22NRFB-LDN-NS-00 is a NEMA 23 size motor and the size of its mounting face is 1.1” square. This model comes with two stacks and can produce a maximum holding torque of 1.79 N-m. in its current configuration, there is no feedback encoder available inside this motor. The shaft of the M22NRFB-LDN-NS-00 is a 1/4 “smooth shaft.

 This motor comes featured with a double shaft – a feature that makes it suitable to be mounted in a broad range of configurations. Users can wire this motor to operate in either series or parallel configuration according to their application requirements. The M22NRFB-LDN-NS-00 contains a rear earth magnet which is incorporated for the implementation of Sigmax® technology. The Sigmax® is an advanced technology that enhances the performance of the motor by concentrating the magnetic flux at strategically chosen points between the stator and the rotor. This motor offers better efficiency than other motors available in this category.

The M22NRFB-LDN-NS-00 weighs around 1.13 kilogram and the detent torque it requires during startup is 0.12 Nm. In a series configuration, this rated current/phase for this model 3.3 amperes and phase resistance is 0.84 ohms. The windings of this motor have NEMA Class B type insulation and the resistance of the insulation is 100 M-ohms at 500 VDC. the power connector of the M22NRFB-LDN-NS-00 can easily be accessed as it is provided at the bottom side motor`s rear end. The 8-wire configuration of this motor brings multiple connection configurations.
