LynxDrive range of compact servo actuators introduced
High precision drive technology expert Harmonic Drive has combined accuracy, compact design and reliability to create the LynxDrive range of compact servo actuators. As a result, the products are ideally suited for the broadcast industry, military and aerospace and oil and gas applications.
The LynxDrive range will also be used in precise positioning applications in high performance machine tools and machining centres, particularly in sectors like factory automation, medical technology manufacturing, the optical industry and semiconductor and solar cell manufacturing.
LynxDrive Servo Actuators combine a compact synchronous servo motor, feedback sensor and a high precision Harmonic Drive HFUC Series Gear Unit with high capacity output bearing. The key advantages of these specifications include low energy consumption, resulting in low running costs, and an extremely compact design; which means the servo actuator fits easily into restricted spaces.
The sinusoidal commutated AC servo motor exhibits a particularly smooth torque profile over a wide range of speeds. LynxDrive Servo Actuators have a torque range of up to 647 Nm and a maximum speed range of 283 rpm. The encoder or resolver feedback system allows the LynxDrive to accurately measure speed and position, while the temperature sensors integrated into the motor windings, ensure protection against overload.
The LynxDrive range of servo actuators works well with commercially available servo controllers that use a 230V to 400V AC supply voltage. Harmonic Drive’s fully digital YukonDrive servo controller works in conjunction with products from the LynxDrive series to create a tailored, innovative and reliable drive system. This makes it possible to provide a single source supply for a pre-configured drive system, whilst still being compatible with almost any controller on the market.
“Most of our servo actuators are used in an extensive range of mission critical applications. Because of this, size, weight and performance requirements have always been crucial to our clients,” explained Graham Mackrell, managing director of Harmonic Drive UK.
“When we developed the LynxDrive range, we focussed our efforts on creating the most compact design possible, without compromising on quality. The combination of low motor inertia and high acceleration torque makes the products perfect for highly dynamic applications and ensures excellent positioning accuracy.”
The high stiffness cross roller bearing used in the LynxDrive servo actuators was developed expressly to withstand high axial and radial forces, as well as high tilt moments. The bespoke bearing also protects the gear from external loads, which guarantees a long life and consistent performance. Removing the need for additional output bearings also means that installation and assembly of the actuator is significantly streamlined.a
