R.T. Gilman’s Mech-Tronix industry standard spindle line will give your process more power, variable speed and more tool connection choices than any other spindle. Select either Totally Enclosed Non-Ventilated (TENV) or Totally Enclosed Liquid-Cooled (TELC). Over three times as much power with the liquid-cooled (TELC) motor. Available with a pre-programmed AC drive and a properly sized motor chiller.

• Embedded thermistor for motor protection.
• Precision components "in-stock" allow for spindle assembly to your specifications. (No grinding after assembly needed!)

R.T. Gilman’s Mech-Tronix (MT) series spindle drives are general purpose, microprocessor-based, software-controlled units representing significant advances in AC drive technology. Design features include comprehensive operator control and programming panel for digital setup, troubleshooting and self-diagnostics. Optional capabilities include remote interrogation, digital speed input and multiple communication options for direct control by programmable logic controllers and computers.

The MT series spindle drive uses sensorless torque control (encoderless) for improved torque control over the rated speed range.

The R.T. Gilman’s MT series spindle drive provides a wide range of adjustable speed control of conventional AC induction motors in applications exhibiting a variety of load characteristics. The unit converts the fixed frequency and voltage of the AC line power source to a sine-coded Pulse Width Modulated (PWM) adjustable voltage and frequency output that will control induction motors over a wide speed range. For complete information on the AC drives applicable to the standard Mech-Tronix spindles, download the catalog 980-615 (2.2 MB).

Drives are designed and manufactured to comply with applicable standards established by the National Electric Code and NEMA for industrial motor and control equipment. They are UL listed and CE compliant.
