High fitting tolerance
Case Study Automation
Most commonly, optical speed sensors are utilized to measure the rotation speed of the rotor units on wind turbines. In general, such speed sensors are susceptible to vibration, dampness, and dust, and have to be protected against dirt for secure operation. In addition, the production of such sensors is difficult for large shafts and is thus expensive. Problems are also caused during operation by heat expansion and stock rotation in the motor units.
Together with a manufacturer of high-quality speed sensors, a robust and maintenance-free magnetic solution with a circumference of 800 mm was developed and produced. The speed sensor is applied directly to the drive shaft without any major mechanical effort, which allows a radial space of 1 mm between the rotary sensor and the sensor unit.
Excellent for large shafts
Extremely small dimensions
Robust against vibration, dampness, dust, and dirt
Large radial and axial space between the rotary sensor and the sensor unit

Using a flexible manufacturing process HSMAG offers scales for arbitrary lengths with different pole lengths. HSMAG uses different accuracy classes for linear scales
A03 +/- 3 microns maximum deviation of a pole boundary of the ideal position
A10 +/- 10 microns maximum deviation of a pole boundary of the ideal position
A20 +/- 20 microns maximum deviation of a pole boundary of the ideal position
A40 +/- 40 microns maximum deviation of a pole boundary of the ideal position
A100 +/- 100 microns maximum deviation of a pole boundary of the ideal position
HSMAG produces linear magnetic scales with one or more tracks. A reference point or index can be written in the second track, which is used as the zero point for the control.

HSMAG products support customers with diverse solutions for rotary measurement, both incremental and absolute. Rotary solutions are used for continuous or discrete positioning, motion control, such as commutaton, and many other solutions.
Rotary measurements requires two components:
Rotary sensing heads
HSMAG develops and produces both absolute and incremental angle measurement solutions. In the combination of individual sensing head and task-specific scale, an optimal rotary measuring solutions can be developed.
