Product Description:

The 12FGT Gear Motor is manufactured by Kollmorgen. It is part of the ServoDisc Pancake DC Motors series. The module is considered an efficient servo module to be used for industrial automation applications.

The <<12FGT Gear Motor is featured with a shaft that can withstand 125 lb maximum force perpendicular to its axis which is important for applications with side forces. It is featured with a tachometer which provides real-time feedback on motor speed which is used for closed-loop control and enhances speed accuracy. It comes in a weight of 6.20 lb. The motor shaft turns 16.06 times for each output shaft revolution which increases torque while reducing output speed. It has an axial length of 3.80 in which affects the available space and how the unit fits into machinery or enclosures. It is able to accelerate and decelerate faster which is ideal for rapid motion control because of its lower inertia of 0.0252 oz-in-sec². The rate voltage required for its normal operation is 19.4 volts. Under rated load it draws 7.4 amperes current which affects power supply requirements and thermal management.

The 12FGT gear motor has a typical output speed of 189 RPM under load. The encoder used for providing precise position feedback is M23 Optical Encoder. It uses brushes that wear slowly and reduces maintenance and extends service intervals. The module is able to produce maximum torque of 7.7 N-m at short time which is useful for handling startup or overload conditions. While it can supply 3.2 N-m torque continuously without overheating. The maximum load the shaft can handle along its axis is 150 lb which is important for applications with pressing or vertical loads.

Frequently Asked Questions about 12FGT:

Q: How does the gear ratio of 16.06:1 benefit the 12FGT Gear Motor application?

A: The 16.06:1 gear ratio significantly boosts output torque while lowering speed. This enhances performance in load-intensive applications needing precise motion control.

Q: Why is the M23 Optical Encoder used in the 12FGT Gear Motor?

A: The M23 Optical Encoder provides high-resolution position feedback. This improves closed-loop control and ensures accurate motion synchronization in automation systems.

Q: What impact does low rotor inertia have on the 12FGT Gear Motor?

A: The 0.0252 oz-in-sec² inertia enables faster starts and stops. It is ideal for applications requiring high dynamic response and minimal overshoot.

Q: How does the long brush life of the 12FGT Gear Motor reduce maintenance?

A: Extended brush life reduces replacement frequency and operational interruptions. It enhances reliability and lowers total cost of ownership over time.

Q: What is the function of the integral analog tachometer in the 12FGT Gear Motor?

A: The tachometer provides real-time speed feedback to the control system. It enables more responsive and stable velocity control in servo applications.
