Drive Solutions
Wavedrive's drive solutions are ideal for high-precision and high-torque rotary motions. Our compact drive systems are made up of our own backlash-free gear drive (strain wave gear or planetary gear set), high-power-density electric motor, optional electromagnetic brake, angular position sensor, integrated motor control unit, and the housing that contains them. The following types are the basis of customer- and application-specific solutions.
WHY THE WAVEDRIVE SYSTEMS?
The variability of our basic drives allows us to offer our partners the optimal solution for their given application. By changing the design, tooth parameters and geometry of the gear drive, the characteristics of the drive (gear ratio, efficiency, torsional stiffness, load capacity) can be fundamentally controlled and made unique. While in an industrial manipulator, a rigid and perfectly backlash-free drive may be attractive, in the X-ray tube rotation unit of a medical diagnostic device, perfectly smooth and noiseless operation and low current consumption is ideal.

WDC CONFIGURATIONS
WDP
The WDP drive system is based on a precision differential planetary gear and a high-power density BLDC motor, offering high positioning speed with negligible backlash. The drive unit includes an incremental encoder mounted on the motor shaft, an optional brake, and an absolute encoder mounted on the output shaft. An integrated, motor control circuit, along with motion control (speed, position and torque control) is available. WDP precision planetary gears can be used in medical technology, in the field of robotics, and are also the perfect choice for custom developments.
WDF
The WDF precision drive system is based on a high-performance BLDC motor driven flat- wheel wave gear, which has excellent torsional stiffness, high gear ratio (80-160) and is completely backlash-free. For precise control the drive unit includes an incremental encoder mounted on the motor shaft, an optional brake, and an absolute encoder mounted on the output shaft. They are recommended for use in rotary tables, industrial manipulators and custom-made equipment.
CONTROLLER
The WD-MC-80 is a universal BLDC motor controller developed for precision positioning tasks. For easy installation, it consists of two panels that can be placed on top of each other, which provide the motor control, the communication and the power supply functions. During the development, our goal was to make a compact circuit that can be fitted into the WDC- WDF-WDP drive systems, which can properly serve our self-developed, high-precision robot joints. It has incremental encoder, Hall sensor and absolute encoder inputs, as well as a brake control function. CAN, RS485-MODBUS and Ethernet communication ensure universal usability and connection to various system control devices. The center of the panels has a hole with a diameter of 20 mm, which allows for use in hollow shaft drives that provide cable routing.
