Plug & Drive PD2-N integrated closed-loop stepping motors from Nanotec Electronic, U.S. (Medford, MA), provide closed-loop sine commutation. They feature 71 oz-in of torque, and speed up to 3000 RPM with near-servo performance. The sine commutation position, torque, and speed control, and 12-bit encoder, are integrated inside the motor envelope. The stepper motors are used wherever speed, high precision, and compact design are required. They are characterized by high-torque stepper motors combined with dspDrive technology developed by Nanotec, and an integrated position control system with an encoder.
