MOTION CONTROL
specific to customer requirements. The standard S3 delivers accelerations beyond 1G, velocities above 5m/s, and class-leading frequency response above 40Hz. There is also fine resolution possible with the ability to have fractions of a millimetre of motion, an attribute appreciated for both road and track users. The new motion control system has also expanded the yaw from 45˚
to 360˚. This full 360˚ dynamic yaw rotation enables the simulator to be capable of representing very tight corner turns, useful in motorsport or, for road cars, it is ideal for testing pedestrian detection systems. Another key innovation is its patent pending mechanism that carries the
cabin. This system offers a further three degrees of freedom (heave, pitch and roll) to the motion profile. This design, developed in-house at Ansible Motion, means a vehicle cabin weighing up to 500kg (up from 300kg on the S2) can be exercised dynamically in all six degrees of freedom (the maximum possible for defining the motion of a body), at any point. This novel solution, using epicyclic gearboxes, avoids the usual, complex interactions between multiple motion controllers in the control system, which can lead to inconsistencies in the motion depending on the current position or velocity of the vehicle. It also eliminates the drastic reductions in usable motion space that can occur with parallel motion systems, and it reduces the complexity of controlling and tuning the motion system for different use cases. Such versatility a key benefit for convincing those with the keys to the capital expenditure. The switch to linear motors from belts has also enabled Ansible Motion to extend the time between services by 100%. “We’ve eliminated the servicing requirements for the carriages and
bearings, reducing maintenance and costs to an annual inspection,” claims Haigh. “That can make a difference to a vehicle programme with less downtime and lower operating costs.” Looking ahead, Ansible Motion has a further three orders for the Delta
series S3, indicating the importance of motion for developing the next generation of road and race cars.

FEATURE high-torque integrated harmonic actuator systems with shorter lead time
Motion Control Products (MCP) has introduced an innovative, compact, high- torque integrated harmonic actuator systems with a shorter lead time up to eight weeks. Offering high levels of torque and precision, the latest harmonic actuator systems have a torque motor with integral harmonic gearbox and optional onboard electronics. With high efficiencies and compact sizes, they are available in two series: MAH and MGM. The all-in-one MGM series has an integral torque motor, backlash-free
harmonic gearbox, high resolution absolute or incremental encoder, brake and servo drive. Delivering a high precision of up to 60 arc sec, high torque of up to 557Nm makes them ideal for applications demanding low noise, high torque and precision control, such as collaborative robot applications. Integrated servo drives for EtherCAT or CANOpen enable the units to interface with most mainstream controllers on the market. A hollow shaft simplifies system design. The other series is the MAH, with standard
hollow shaft and frame sizes from 75-170mm diameter. Peak torques of up to 800Nm are available and precision is up to 30 arc sec. Both series are flexible, reliable, low
maintenance and compact. Gear ratios are available from 51:1 to up to 161:1. All models are fully enclosed and self-cooled and can be specified with IP67 ingress protection when operation is required in harsh environments. Standard input voltages are 48VDC, 110VAC and 220VAC, and input voltages, torque, etc. can be customised. As well as robotics and factory automation, applications for the versatile
motors include electronic and semiconductor equipment, medical equipment, precision measuring instruments, etc.
