Product Description:
The E22SSLT-LNN-NS-02 is a hybrid stepper motor manufactured by Kollmorgen within the E Hybrid Stepper Motors series. Intended for incremental motion control in automated machinery, it translates pulse commands into fixed angular increments so that tables, slides, or gauges can index repeatably without feedback devices. SIGMAX construction intensifies the magnetic circuit for higher torque density, while a smooth shaft allows direct coupling to gears or pulleys. The motor is wired in a four-lead series configuration, making it compatible with most bipolar stepper drives used with low-to-moderate bus voltages.
The frame conforms to NEMA 23 dimensions, enabling direct mounting on equipment already drilled for that footprint. Each command pulse advances the rotor by 1.8°, resulting in a resolution of 200 steps per revolution before microstepping is applied. Positional deviation is limited to ±1.5% of a full step, minimizing cumulative error across long motion sequences. Torque generation is increased by the motor’s two-stack design, which enlarges the active magnetic length without increasing the frame dimensions. The motor has a winding optimized for maximum torque at low speed, so holding torque and low-speed pullout torque remain high for direct-drive lead screws and indexing plates.
The motor uses Class B insulation rated for 130 °C, allowing the windings to operate at elevated temperatures during high-duty cycles without insulation breakdown. Its dielectric strength is rated at 340 VDC, providing electrical separation between the winding conductors and the motor housing. Insulation resistance remains at least 100 MΩ, helping reduce leakage current when the motor operates in humid industrial areas. Safe ambient operation spans −20 °C to +40 °C, covering typical production-floor temperatures without auxiliary heating or cooling. The smooth shaft provides a straightforward interface for clamping couplings, while the compact NEMA frame supports installation where mounting space is limited. Its fixed angular movement also allows a compatible drive to control position through an accurately counted sequence of command pulses.
