ServoTek Products Inc., a world-renowned manufacturer of instrument-grade DC tachometers and low-cost encoders, announced the successful application of its TachSyn Series brushless DC tachometer/commutator within industrial motor speed monitoring applications.

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.

Servo-Tek Tach Generators provide a convenient means of converting rotational speed into an isolated analog voltage signal suitable for remote indication and control applications.

Combining high accuracy with low driving torque, Servo-Tek tach generators are ideal for use in servo systems.  Tach Generators are particularly suited to application in precision integrators and velocity servos, both of which require a highly linear speed/voltage relationships with minimum ripple.

DC Tachometer Generators are also excellent rate generators for velocity damping in position servos.Servo-Tek Tachometer Catalog

Servo-Tek Tach Generators provide a convenient means of converting rotational speed into an isolated analog voltage signal suitable for remote indication and control applications.

Combining high accuracy with low driving torque, Servo-Tek tach generators are ideal for use in servo systems.  Tach Generators are particularly suited to application in precision integrators and velocity servos, both of which require a highly linear speed/voltage relationships with minimum ripple.  DC Tachometer Generators are also excellent rate generators for velocity damping in position servos.   Features include:

Speed Transducers/DC Tach Generator
The nearly pure dc output-with no phase shift-allows Servo-Tek Tach Generators to be used as feedback transducers for numerous types of equipment, including fast-response servos and other devices.

Tach Generator Construction
Servo-Tek Tach Generators are housed in aluminum casings protected in accordance with Mil-C-5541 or Mil-A-8625. Alnico permanent magnets are used. Armature shafts are stainless steel, and rotate on fully-shielded stainless steel ball bearings. Commutators are made from an alloy containing 95% silver. Armature laminations are wound with Isomid insulated wire, over Teflon slot insulation. The entire armature is impregnated and baked, resulting in a NEMA Class H insulation system.

Brush Life
Tachometer Generator brushes and commutators are matched for long life and stability. Operation at 1 mA output will deliver maximum brush life.

Linearity
Linearity, of Servo-Tek DC Tach Generators, at any speed is better than 0.1% of the output at that rpm.

Ripple
The DC Tachometer Generator ripple rms value will not exceed 3% of the dc value at any speed in excess of 40 rpm on standard units; 1.5% on low-ripple models. 

Bidirectional Operation
All Servo-Tek DC Tach Generators operate in either rotational direction. That direction can be determined by output voltage polarity. Output (in either direction) is held to a tolerance of 0.25% of the average output.

Stability
Optimum brush and commutator combination gives 0.1% stability. Highly stable output gives no evidence of long-term drift.

Temperature Range
Tachometer Generators are designed for continuous operation in ambient temperatures ranging from -55°C to +100°C(-67°F to +212°F). Voltage output at 25°C will not deviate by more than 0.01% per degree of change within the range of -20°C to +75°C.  All Tachs are temperature compensated, with the exception of Series D and E.
