Built on Finding Solutions

Our history has always been shaped by solving what was in front of us. From powering a small radio on a rural farm to building motors and inverters for ships and aircraft during World War II, each part of our history has come with different challenges. But it has always been about finding the best way to solve them.

That same mindset still shapes how we work today.

High Torque in a Tight Space

A commercial baking equipment manufacturer came to Groschopp looking for a motor that could be used across four different applications on a bread packaging machine.

The challenges included:
• Tight space requirements
• High torque in a small package
• Duty cycles ranging from continuous operation to direction changes every second or less
• Brush life concerns in short oscillating duty cycles

Groschopp developed a custom brushless DC motor with a ten-pole, 12-slot design to deliver high torque in a compact package. New bearings helped increase the expected motor life to 50,000 hours.

Gearmotor Basics: Parallel Shaft Reducers

Parallel shaft gearboxes are a common reducer option for many types of equipment. They are often used when equipment needs reliable performance during continuous operation.

A few common characteristics:
• Uses helical pinion gears and spur gears
• Offers high efficiency ratings
• Works well for continuous duty applications
• Provides good overhung load capability

Choosing the right motor often means looking beyond basic specs.

When a motor is being evaluated for a specific application, testing can help show how it performs under real operating requirements.

Some of our motor testing capabilities include:
- Speed and torque testing
- Thermal testing
- Gear reducer efficiency testing
- Extreme duty cycle testing
- Sound analysis
- Gearmotor life testing

Testing gives a clearer picture of motor performance and helps support a better fit for the application.
