Compact 90 mm AC Drive Engineered for Efficiency
The INDUCTION MOTORS 90 mm 120 W embodies the ideal small AC Motor solution—delivering 120 W continuous power within a compact 90 mm frame and total motor weight around 3.4 kg. Designed for real-world industrial conditions, it operates smoothly across –10 °C to +50 °C and up to 85 % relative humidity. Paired with a planetary gearbox weighing just 1.5 kg, mechanists benefit from a sleek, space-saving planetary gear motor setup without sacrificing robustness or thermal tolerance.

Precision Speed and Torque Customization via Gear Ratios
Configurable gear reductions ranging from 3:1 to 200:1 enable output speed from 3,500 min⁻¹ down to as low as 7.5 min⁻¹, while delivering torque from 2.3 Nm (low ratio) up to 20 Nm at ratios above 40:1. This flexibility empowers designers to fine‑tune motion control precisely, shifting seamlessly between rapid actuation and slow, high‑force output—an attribute that elevates this AC Motor above generic designs.

Built for Continuous Industrial Reliability
Engineered for dynamic loads, this drive handles up to 500 N radial and 150 N axial loads at a 25:1 ratio, ensuring mechanical integrity during prolonged operations. The integration of motor and gearbox into a unified assembly reduces mechanical wear and simplifies system architecture—reinforcing Caida’s reputation among leading ac motor manufacturers and ac motor suppliers for building performance-centric, durable planetary gear motor systems.

Product Advantages

High Power Density in Compact Form
Despite its modest 90 mm frame, this small ac motor delivers 120 W of continuous output. Its compact dimensions and integrated planetary gear box make it ideal for space-constrained system designs seeking high performance.

Broad Range Gear Options
With gear ratios from 3:1 to 200:1, this AC Motor and planetary gearbox combination allows precise adaptation of operational speed and torque, facilitating versatile application in automation tasks requiring customizable motion profiles.

Exceptional Load Capacity and Reliability
Supporting radial loads up to 500 N and axial loads up to 150 N, the gearmotor maintains performance under sustained mechanical stress. This robustness elevates Caida among top ac motor suppliers offering durable planetary gear motor solutions.

Use Scenarios

Light-Duty Conveyor Drives
For compact conveyor systems, selecting gear ratios between 25:1 and 60:1 ensures balanced throughput and torque, using this planetary gear motor for dependable conveyor performance in packaging or assembly lines.

Precision Access Control Systems
High gear ratios (150:1–200:1) deliver slow, controlled motion—perfect for sliding doors, shutters, or access gates. This small ac motor with gearbox provides safe, precise actuation ideal for security and access applications.

Laboratory and Test Equipment
Low-speed, high-torque output (e.g., 7.5 min⁻¹ and 20 Nm) makes this motor ideal for lab automation—such as sample rotation, platform positioning, or calibration drives—where accuracy and reliability are critical.
