Product Description:
The M093-TE11 is a hybrid stepper motor produced by Danaher within the Slo-Syn Stepping Motors series. It converts digital pulse trains from an indexer or PLC into incremental shaft motion for positioning conveyors, actuators, and metering devices in industrial automation. Each input pulse advances the rotor by a fixed increment, allowing open-loop speed and position control without feedback devices. This operating method supports repeatable movement when the load remains within the motor’s available torque range.
The motor completes a revolution in 200 full steps, with a step angle of 1.8° and a cumulative step-position error limited to ±3%. In a bipolar parallel configuration, the winding draws 7.8 A and has a phase resistance of 0.24 Ω with an inductance of 3.2 mH. This electrical arrangement produces a holding torque of 550 oz-in. In a unipolar configuration, the phase current is 5.5 A through a coil resistance of 0.48 Ω, and the static torque reaches 450 oz-in. These electrical values support drive and power supply selection while helping determine the available stall margin under load. The winding characteristics also affect current decay rates and the smoothness of microstepping operation.
The motor tolerates shaft side loads up to 25 lb and axial thrust loads up to 50 lb, allowing it to support timing belts or lead-screw assemblies without excessive bearing stress. Rotor inertia is 0.0265 oz-in-s², providing moderate acceleration capability while helping damp resonance at low pulse rates. A residual torque of 7.0 oz-in provides detent holding when the coils are de-energized, which improves positional stability during a loss of power. Because this residual torque is low compared with the allowable mechanical loads, energized holding current should be maintained when the connected load requires greater stationary torque. The unipolar drive voltage is limited to 2.6 VDC, helping control winding heat during high-duty-cycle indexing. Proper current regulation is necessary to prevent thermal overload while preserving the expected torque output.
