As of March 26, 2010 Joliet Technologies is no longer representing the Avtron line of products.

We do however represent the Dynapar line of Rotary Feedback Products.

Avtron – Tachs, Tachometers, Encoders, Rotary Pulse Generators

Joliet Technologies is the preferred Avtron Integrator for the Chicagoland area.

M3 Applications

Three styles of M3 available, depending on application

NEMA 56C Face Mounting

M3 NEMA 56C Face Mounting

Figure 1 – NEMA 56C Flange Mounting

On motors equipped with a 4.5″ adapter flange, the M3 will mount directly on the C-Face and couple to the motor using a standard coupling (Figure 1).The M3 can update or replace any NEMA 56C face mounted device, including many older styles of Avtron Pulse Generators like the M737A.When used in conjunction with a frequency to voltage converter like the Avtron Model K661, it can replace analog tachometers like the BC46, BC42, and RE210.

Hollow Shaft Mounting

The hollow shaft capability of the M3 makes it perfect for a wide variety of special mounting applications. With the hollow shaft configuration, no C-Faces, couplings, or adapter flanges are required. On new motors, this greatly reduces the overall installed cost when compared to other styles of pulse generators. The M3 can be mounted on shafts ranging in size from 0.625″ to 2.375″ in diameter.With this large diameter capability, the M3 can be used on large frame motors without the need for a specially engineered stub shaft. The actual non-drive end motor shaft can be used.For standard AC motor mounting, the M3 can be mounted outboard of Totally Enclosed, Fan-Cooled (TEFC) motors (Figure 2), on Totally Enclosed, Non-Ventilated (TENV) motors (Figure 3), on motors equipped with disk brakes (Figure 4), and inboard of fans on motors with separate ventilation (Figure 5).Consult your motor supplier for specification requirements.

Foot Mounting

M3 Foot Mounting

Figure 6 – Direct Coupling, Foot Mounting with Bracket

The M3, can be directly coupled to motors and shafts without a machined C-Face, by using the foot mounting bracket. This bracket has a footprint that matches other Avtron heavy, mill-duty pulse generators. The advantage of this bracket is that you only need to align the bracket once and mount the M3 on its C-Face. If replacement of the M3 is needed, simply remove the M3 from the C-Face bracket and install a spare. No realignment is required (Figure 6).
