DC servo motor

Integrated motor controller

With the PD6-C, Nanotec (Germany) introduces a brushless DC servo motor with integrated controller that delivers high power density in relation to its size. Reference values can be set via CANopen.

THE PD6-C IS THE LARGEST MOTOR of the company’s Plug & Drive family and is available in two versions: as a high-pole stepper motor in various lengths with a maximum nominal torque of 8,8 Nm, as well as a low-pole BLDC motor with a flange size of 80 mm or 86 mm and a nominal output of 534 W. Both motor types are designed for 12 V to 48 V supply voltages.

The motor controller and the encoder with 4096 increments are integrated in the motor, therefore cabling is limited to the communication connection and power supply. All motors of this family use field-oriented control via encoder and can be operated in torque, speed, or positioning mode. Reference values are set either by clock-direction, two analog inputs, or CANopen.

The controller is programmed with the programming language NanoJ V2 so that real-time programs for time-critical applications can be run directly on the motor. In stand-alone operation the motor carries out complex control tasks without a fieldbus connection. For parameterization, a USB port is available. The PD6-C is suited for applications that require high power density and high efficiency as well as compact size, for example in service robotics or mechanical engineering.
