SERVO DRIVES FOR DIRECT DRIVE MOTORS

Direct drive motors are the best choice when high precision and compactness is required. Rotary direct drive motors are often referred as Torque Motors due to the ability to produce high torque at low speeds. This type of motors are most commonly provided as frameless motor kits in order to integrate them into the system mechanics and have a large number of poles and low inductance characteristics. Servo Drives for direct drive motors require high switching frequencies in order to precisely control the torque of the low inductance motors and and high commutation and servo loop update rates in order to provide high stiffness at low speeds. Ingenia has a wide experience on delivering both off-the-shelf and custom solutions for robotic applications using torque or direct drive motors. Explore our range of standard and custom servo drives for direct drive motors and find the right solution for your application.

How does a Direct Drive Motor Controller Work?

Servo drives designed for torque, frameless or direct drive motors require high switching frequencies in the range of 40 to 125 kHz depending on the motor electrical time constant. This is achieved by using transistor technology with low switching losses and perfectly tuned gate drivers in order to control the heat generated by the servo drive. As direct drive motors typically have a large pole count, the motor controller must be able to handle high electrical frequencies to properly and efficiently commutate the motor.

Direct drive motors are linked directly with the load. This implies that in order to have a good accuracy, high resolution encoders must be used and in order to prevent homing procedures on startup, absolute encoders are preferred.

Benefits of Direct Drive motor servo drives

Servo drives designed specifically for direct drive motors provide the best performance from your motor:

  • Can be integrated directly on the same joint as the frameless motor reducing cabling complexity.
  • High stiffness and precise control due to high servo loop update rates.
  • High power stage switching frequency eliminates the need of bulky chokes that also generate heat.
  • Fast EtherCAT communications with low latency provide deterministic, real time control.
