The high-accuracy TachSyn may be used as either a brushless DC tachometer or brushless DC motor commutator for monitoring the rotational speed of brushless industrial DC motors. They offer an economical solution to many velocity-loop problems, whether brushless or standard servo. The robust design of the ServoTek Products TachSyn transducer consists of a primary magnetic sensing device, in which output windings, field winding, and a permanent magnet are all co-located within the stator itself, maximizing reliability. The transducers are available in several unique models to commutate 4-, 6-, or 8-pole brushless DC motors. Any sized TachSyn tachometer may be specified in applications where a simple DC tachometer signal is the only requirement. Pancake-shaped TachSyn transducers are easily mounted, cantilever- style, to the back of a motor or other device, with synchro-type adjustment for phasing.
Each TachSyn transducer requires one CT-4 Series circuit board (or a customer-supplied equivalent), as well as a connecting cable with double-barreled shield to complete signal conditioning. The CT-4 circuit board provides AC field excitation for the transducer and conditioning for its output signals, which include a linear low-ripple DC tachometer voltage, and either a Hall-equivalent or sine-wave commutation signal. The circuit board may be housed up to 100 feet from the hot-running motor, leaving only the non-electronic transducer in close proximity. Standard configurations are normally in stock, and may be ordered online via the company’s website.
