Product Description
The Y-2012-2-H04AA, a Y-series motor from Rockwell Automation, offers brake options and can be converted to a TL-Series (Bulletin TLY) Motor, specifically the TLY-A230T-HK64AA. Designed using metric dimensions, inch values are approximate conversions. Its product number, like those of other series, encodes specific options: 'Y' denotes the series; '2012' the frame size; '2' the winding voltage; 'H' the encoder line count; '04' (24V DC brake); and 'AA' special factory options. Typically featuring 230V windings, the Y-2012-2-H04AA reaches 4500 RPM with a 1.4 N-m continuous stall torque and 3.8 N-m peak stall torque. Its 0.51 kW rated output allows operation with maximum radial (25 kg) and axial (10 kg) shaft loads. Compatible drives include 2094-ACxx-Mxx-S or 2094-AMxx-S (incremental feedback) and the 2090-UXNFBY-Sxx motor feedback cable. These servo motors require careful installation and are not for direct power supply connection. Ensure proper mounting before operation and use a drip loop in downward-pointing cables.
Is Your Device Showing These Signs?
The Allen Bradley Y-2012-2-H04AA servo motor commonly exhibits issues related to resolver feedback malfunction, resulting in inaccurate positioning and velocity control. Technicians address winding insulation degradation, leading to short circuits and motor failure. Bearing wear is a frequent problem, causing excessive noise, vibration, and eventual rotor damage. We repair damaged connectors and wiring, ensuring proper signal transmission and power delivery. Overheating due to inadequate cooling or excessive load is resolved through thermal management solutions and load optimization.
