Product Description:
The H22SSLB-LNN-NS is a hybrid stepper motor manufactured by Kollmorgen as part of the H Hybrid Motors series. It converts timed step pulses from a drive into discrete shaft movements, allowing pick-and-place heads, indexing tables, and small conveyor gates to position loads without encoder feedback. The motor has a standard configuration and a smooth shaft that can be secured to compatible clamping pulleys or couplings. Its compact design makes it suitable for moderate-torque positioning axes with limited installation space.
The motor mounts on a NEMA 23 flange, so it fits brackets that use the corresponding frame mounting pattern. The windings have Class B insulation rated for 130 °C, which maintains dielectric strength as internal temperatures rise during operation. An insulation resistance of 100 megohms minimizes leakage current between the phases and motor frame. The insulation system has a withstand voltage of 340 VDC, helping it tolerate overvoltage events originating from the drive. Electrical hookup uses a four-lead series arrangement, providing two conductors per phase for connection to a compatible bipolar stepper drive. A two-stack laminated core increases the available magnetic flux while the standard housing maintains a compact overall length.
Each full step advances the rotor by 1.8 degrees, producing 200 discrete positions per revolution for straightforward conversion into linear movement through lead screws or belts. Step accuracy remains within ±1.5%, supporting repeatable motion across normal operating cycles. The motor operates at ambient temperatures from -20 °C to +40 °C, allowing use in cool industrial spaces and temperature-controlled production areas. The smooth shaft transfers torque through a properly fitted clamping connection without requiring a keyway. Open-loop operation reduces system complexity when the commanded load and acceleration remain within the motor’s available torque range. The drive can also use microstepping to divide each full step into smaller increments for smoother movement and reduced vibration.
