With a deep knowledge and a service minded and flexible approach we help clients solve advanced motion challenges!

Compact Motors

Our innovative and unique stator design enables us to combine high torque with a very compact design into the most efficient and dynamic PMS servomotor on the market. The technology means that our industrial servo motors are up to half the size of our best competitor.

Special Motors

HDD innovative stator and modular design system combined with a highly skilled design team creates a unique ability to customize our industrial servo motors to specific needs and with a cost-effective production even in small volumes.
Solid Shaft Motors

HDD Solid Shaft is our most sold servo motor. Available in a torque range from 1.2 Nm to 10 Nm, rated 3000 or 6000 rpm and wound for 230 or 400 VAC.  The motor is equipped with keyway, straight connectors, resolver feedback, PTC thermal sensor and IP-65 protected and can be supplied with a brake.

Hollow Shaft Motors
The Hollow Shaft Motors have the same excellent power and torque density properties as the solid shaft servo motors, but with a hollow shaft.
Internal Coupling Motors
The unique HDD technology with an integrated bellow coupling, enables a more compact installation of servo motors.
Low Voltage Motors
Servo motors controlled by a low voltage driver. Low Voltage is available for our Solid shaft, Hollow Shaft and Internal Coupling Motors.
Open Frame Motors
HDD offers open frame or frameless motors for direct integratin in your application. Integrating the stator direct into your housing reduces size and weight.
Ball Screw Motors
DD’s ball screw servo motor transforms the motor axel rotation to an axial movement. The ball screw servo motor is designed to directly drive a spindle nut.
Custom Servo Motors
A customized servomotor allows our customers to create a competitive advantage for their products.
