T21NRLH-LNN-NS-00

Product Description

The T21NRLH-LNN-NS-00 is a high torque motor from the renowned motor manufacturer Pacific Scientific. The motor features enhanced torque linearity that is capable of rendering high peak torque capability. The unit features a two-phase design. The T series stepper motor produces low detent harmonic torque and generates more torque than its three-phase or five-phase counterparts in the industry. It does not generate feedback. However, the motor comes with the provision for mounting an encoder on the shaft if needed. The device needs less input power for its operation compared to three-phase motors that generate the same torque.

The stepper motor generates high torque even when functioning at a moderate speed. The unit is enclosed in a 2.25” square rugged housingless NEMA 23 size frame. It also produces low detent harmonic torque. The device supports terminal box construction and encompasses a removable cover. This makes the #22 AWG leads easily accessible. The hybrid motor features leadwire connection using four leads connected in series. The unit comes with a laminated rotor that has 1 stack length. It is not as expensive as servo motors. The motor can be used with most drivers and offers a smooth microstepping performance.

The high torque unit has a smooth double-ended shaft with no rear shaft extension. The motor is apt for use in systems intended for intermittent duty applications. It has 1.27Nm holding torque, 0.0212Nm detent torque, 4.64°C/Watt thermal resistance and very low rotor inertia of 0.0248kgm² x 10^-3. The unit features regular lead wire hookup or construction. The device also incorporates H type winding and NEMA 23 mounting configuration. The small size of the motor makes it suitable for use in areas where space is a challenge. It has an overall size of 2.21 inches without the terminal box while each lead is about 12 inches long. The optimized magnetics offer assurance of maximum performance with a small size.
