Feldkirchen, September 2012 – Drive specialist Nanotec Electronic has expanded its offering of integrated stepper motors with the compact Plug & Drive PD2-N. The size 42 model (NEMA 17) is ideal for drive applications where the entire unit needs to be of a small size. The position control system and encoder are integrated together with the motor in one housing. The entire unit is very compact with an overall length of only 72 mm. The holding torque is 50 Ncm. Integrated Plug & Drive stepper motors are used wherever speed, high precision and compact design are required. They are characterized by high-torque stepper motors combined with especially smooth-running dspDrive technology developed by Nanotec and an integrated position control system with an encoder. The PD2-N model is the first motor of the Plug & Drive line from Nanotec that integrates a magnetic 12-bit encoder. The PD2-N can be operated in closed loop mode. Through this field-oriented control with sine commutation, stepper motors run with real torque control, high precision and with low resonance. Stepping errors are compensated for during motion and load angle errors are corrected within a full step. As a result, a closed loop stepper motor behaves in a similar way to a high-pole servomotor and can be used in many applications requiring high torque at low speed as an alternative to a servomotor with gearbox. The PD2-N is compatible with RS485 or CANopen and recently became available as a series product. We will also be exhibiting the PD2-N at the SPS in Nuremberg: Hall 4, Booth 582.
