Product Description:
The 104-8011-1 tachogenerator is built by Sanyo Denki and supplied in the SANUPS Power Supplies series. Mounted at the end of a drive shaft, it converts rotational velocity into a proportional DC output that motion controllers and speed regulators can read, providing closed-loop feedback for conveyors, packaging machines, and other automated equipment. The electrical signal tracks shaft speed directly, eliminating the need for an optical encoder in applications where contaminants favor a simple analog transducer. The device supports new and existing systems that require reliable speed sensing with minimal wiring.
The housing forms a cube measuring 70 × 70 × 70 mm, allowing the device to fit within limited gearbox or fan-cowling space. A circular mounting face with a diameter of 60 mm centers the generator on compatible motor flanges. The output shaft measures 8 mm, allowing it to connect through commonly available flexible couplings. Its mass of 672 g keeps the additional overhung load low for motors equipped with sleeve or ball bearings. The compact housing also reduces the amount of clearance required around the motor end shield. These dimensions allow speed feedback to be added without substantial changes to the surrounding machine layout.
The unit is intended for on-motor installation, placing the sensing element close to the drive shaft to reduce errors caused by torsional windup. A one-pole magnetic circuit produces a DC waveform that supports straightforward calibration in drives using a linear transfer function. When the rotor reaches 1000 rpm, the generator delivers 30 VDC. This output is high enough to resist the effects of line noise while remaining compatible with typical analog input cards operating within a 24-to-48 V range. The direct shaft connection allows the feedback voltage to rise and fall with motor speed without additional signal conversion at the sensing point. The analog output can be routed to a motion controller or speed regulator through a relatively simple wiring arrangement.
