42-mm flange-size BLDC motor supports CANopen

Trinamic (Germany) has launched the Pandrive PD42-x-1670 device series. The product comprises a stepper-motor with integrated Hall sensor.

“Trinamic pioneered the market of smart motors more than 15 years ago with launching the first Pandrive: a stepper-motor with integrated driver and bus interface. With the PD-1670 we launch now our first BLDC servo with field-oriented control,” explained Michael Randt from Trinamic. “The compact drive enables machine builders to implement rapid, precise, and efficient positioning in no time.”

The product family features Trinamic’s first smart motor solution with brushless DC motors. The 42-mm flange-size motors have an integrated Hall sensor for closed-loop FOC-based operation. The drives are designed for 4000 rotations per minute nominal velocity and a 6,25-Ncm to 18,5-Ncm rated holding torque.

Suitable for laboratory automation, machine control, robotics, and CNC applications, the drives come with two CAN-based communication options: CANopen (CiA 402) or TMCL, a proprietary higher-layer protocol. Parameters can be permanently stored on the board itself and the drive takes care of all time-critical operations such as ramp calculations itself, ensuring low CAN busload.

The mechatronic solution includes state-of-the-art field-oriented motor control and power driver circuitry. A Hall-based rotary feedback system makes it reliable and durable. The drive is designed to work with a 24-V power supply. Available from March through Trinamic’s distribution channels, the products come in three different lengths, each having 42-mm flange-size brushless motors.
