GAL (G3L Frame Size 50 Aluminum Gear Motor)

Specifications

How to choose Induction Gear Motors

Points to check when selecting, with the values for this product (GAL (G3L Frame Size 50 Aluminum Gear Motor)).

1. 1. Determine Motor Capacity from Required Output

   This product: Motor capacity 0.4 to 2.2 kW

   Calculate the required power from the load torque and required rotational speed, then select a rated output with a margin. Listed products range from 0.1 to 2.2 kW. Insufficient capacity causes overheating and starting failure, while excessive capacity reduces efficiency and increases equipment size.

2. 2. Match Output Speed Using the Gear Ratio

   This product: Reduction Ratio 1/600 / 1/750 / 1/900 / 1/1200

   The output shaft speed is the motor speed divided by the gear ratio, and it varies with the power supply frequency (50 Hz/60 Hz) and number of poles. Select a gear ratio that matches the required speed on the equipment side, and verify the rotational speed at the frequency used in the installation region.

3. 3. Do Not Exceed the Allowable Output Shaft Torque

   A larger gear ratio increases output torque, but the gears and bearings of the reducer have allowable limits. Apply factors for starting and impact to the load torque, and select a frame size and gear ratio combination that stays within the allowable output shaft torque.

4. 4. Verify Power Supply and Destination Standards

   Confirm that the number of phases (single-phase or three-phase), supply voltage, and frequency match the installation site power supply. For equipment exported overseas, compliance with standards such as UL, CE, and CCC, or with high-efficiency regulations such as China's GB Grade 3, may be required.

5. 5. Compatibility of Frame Size, Mounting, and Shaft Arrangement

   This product: Frame number 50

   The frame size indicates the gearhead frame size and is related to mounting dimensions and output shaft diameter. Check it together with foot or flange mounting and the parallel shaft, right-angle shaft, or hollow shaft type. When replacing existing equipment, confirm that the mounting dimensions are identical.

6. 6. Mass and Use of Weight-Reduced Models

   This product: Mass 33.0 kg

   Listed products have a mass of 33 to 42.7 kg. Products with an aluminum gearhead case are reported to be 29 to 37% lighter than conventional models. Consider them when reducing the workload of assembly or simplifying the equipment frame.

About Induction Gear Motors and all products

Description

A lightweight type with an aluminum gear head case. It is a three-phase induction gear motor rated 0.4 kW to 2.2 kW, available with options including brake, waterproof, and IPM specifications. Part of the wooden crate packaging has been changed to reinforced cardboard to reduce the burden of transportation and disposal. The use of aluminum material also reduces CO2 emissions during part manufacturing.
