For laboratory automation and applications with size restrictions, Nanotec has developed an EC motor with a flange dimension of 42 mm and integrated motor controller and encoder. The PD2-C is available as a stepper motor with an operating voltage of 12-48 V and a rated torque of 0.5 Nm as well as a BLDC motor with a rated power of 105 W and a peak power of up to 315 W. Due to its field-oriented control, the stepper motor behaves like a high-pole DC servo – with a higher torque but lower rated speed than a BLDC motor. Therefore many applications can be realized without a gearbox. The controller is also available in two versions: In the stand-alone variant with USB connection, the motors are actuated either via clock-direction or by a set value specified on the analog input. In the CANopen variant, they are actuated via fieldbus according to CiA 402. Both versions support application programs that are executed directly in the motor controller. Due to their low installation effort as well as their modest space and component requirements, Plug & Drive motors from Nanotec are an extremely effective and economic drive solution wherever high precision and maximum benefit must be combined. They also deliver high positioning accuracy (< 0.09°) under different loads and exhibit good synchronization properties.
