SINCOS: Linear Power Stage
Phytron
Linear Stepper Motor Power Stage with Variable Current Profile
The SINCOS Power Stage:
SINCOS is a linear stepper motor power stage particularly developed for applications which require very high step resolution, such as: measuring tables, machine tools, graphic instruments, etc. SINCOS is specially recommended for applications where chopping is not acceptable. The linear power stage SINCOS is able to control stepper motors nearly without noise voltages. SINCOS is the power stage for extreme requirements (e.g. measuring applications), where sensible measuring could be disturbed by perturbing radiation. EMC trouble has not to be expected because of the fully linear design.
