New 1PC JSCC Standard Motor 90YS120GY22

Engineer's Quick Brief

• Continuous Duty Standard Motor: The "YS" designation indicates a standard, constant-speed AC induction motor designed for continuous S1 duty cycles in demanding industrial environments.
• 3-Phase 220V Configuration: The "GY22" suffix specifies a Three-Phase 220V AC input. This provides smoother torque delivery and higher efficiency compared to single-phase equivalents, ideal for inverter (VFD) driven speed control setups.
• Pinion Shaft Design: The "G" in the model code denotes a helical pinion shaft, meaning this motor is engineered exclusively to mate seamlessly with JSCC 90mm gearheads (such as the 90GK or 90GF series) to achieve the desired torque multiplication.

SEO Introduction

The JSCC 90YS120GY22 is an industrial-grade, 120-watt standard AC induction motor renowned for its robust continuous-duty performance in automated material handling and packaging machinery. Manufactured by JSCC (精研), a leader in precision micro-gearmotors, this unit utilizes a 90mm x 90mm square frame designed for high-density mounting. Crucially, the "GY22" nomenclature dictates that this is a 3-Phase 220V motor. This specific electrical configuration is highly favored by system integrators using Single-Phase 220V to Three-Phase 220V Variable Frequency Drives (VFDs), allowing for precise frequency-based speed control without the overheating issues associated with traditional voltage-dimming controllers. Featuring a precision-machined helical pinion shaft, it is designed for direct integration with JSCC planetary or right-angle gearboxes, delivering ultra-quiet, vibration-free mechanical power transmission.

Technical Specifications

Application Matrix

• Automated Conveyor Systems: Provides reliable, continuous rotational power for belt and roller conveyors in logistics hubs and food processing lines, maintaining stable speed under varying loads.
• Packaging Machinery: Integrates with 90mm right-angle gearboxes to drive rotary index tables and sealing mechanisms where smooth, three-phase torque delivery is critical to prevent mechanical jitter.
• VFD-Driven Automation: Acts as the perfect prime mover for applications requiring VFD (Variable Frequency Drive) integration, allowing for programmable ramp-up/ramp-down profiles using a 220V 3-phase output inverter.

Troubleshooting & FAQ

• Can I connect the 90YS120GY22 motor directly to a standard 220V wall outlet? No. Standard wall outlets are Single-Phase 220V. The "GY22" suffix means this is a Three-Phase 220V motor. If you connect it directly to single-phase power without a starting capacitor modification, the motor will hum, fail to rotate, and quickly burn out. You must use a 3-Phase 220V supply or a VFD that converts 1-Phase 220V to 3-Phase 220V.
• The motor is running, but the output shaft has no usable torque to drive my pulley. Why? This is a "Pinion Shaft" motor (denoted by the 'G'). The output shaft features cut helical gear teeth designed exclusively to mesh with the input stage of a JSCC gearbox. It cannot and should not be used as a standalone round-shaft motor to directly drive belts or pulleys.
• How do I reverse the rotation direction of this motor? Because it is a 3-phase motor, reversing the direction is extremely simple and safe. Simply swap any two of the three main power input wires (U, V, W) at the motor terminal or contactor.
• The motor feels very hot to the touch during operation. Is it failing? Not necessarily. Standard industrial induction motors are designed to operate at elevated temperatures. A surface temperature of 70°C to 80°C (158°F to 176°F) under full continuous load is considered normal. Use a thermal camera to verify, and check the amp draw with a clamp meter to ensure it does not exceed the rated current on the nameplate.

Cross-Reference Guide

Understanding JSCC's rigid nomenclature is vital for ensuring you order the correct replacement. Do not mix up the voltage or control type suffixes:

• Single-Phase 220V Alternative: If you do not have 3-phase power and need to plug into standard 220V mains, you must order the 90YS120GV22 (The "V22" indicates Single-Phase).
• Three-Phase 380V Alternative: For heavy industrial grids utilizing standard 380V power, order the 90YS120GY38.
• Speed Control Required? If your application requires built-in analog speed control rather than VFD control, switch from the "YS" (Standard) series to the "YT" (Speed Control) series: e.g., 90YT120GV22.
• Compatible Gearheads: Must be paired with JSCC 90mm gearheads, typically the 90GK (Standard) or 90GF (Heavy Duty) series, followed by your desired gear ratio (e.g., 90GK50H).
