1. Where to Find the Product Selector

You can access the full SlimTorq™ product catalog and datasheets under:

Products → SlimTorq™ Motors

Directly below the product overview, you will find the Product Selector tool, designed to help you filter through available motor configurations based on your application requirements.

2. Understanding the Two Modes

The Product Selector offers two filtering modes:

Basic Mode

Designed for quick and efficient filtering using core system constraints such as:

• Outer diameter
• Length
• Mass
• Supply voltage
  ‍

This mode is ideal for early-stage feasibility assessments.

Advanced Mode

Provides additional filtering parameters for deeper optimization, including:

• Continuous torque
• Continuous current
• No-load speed
• Electrical limits
  ‍

Advanced Mode is recommended when performance targets are clearly defined and system-level trade-offs must be evaluated.

3. Example: Filtering Motors in Basic Mode

Let’s consider a project with the following constraints:

• Maximum outer diameter: 80 mm
• Maximum length: 25 mm
• Maximum mass: 300 g
• Supply voltage: 24 V
  ‍

After entering these values, the results table automatically updates to display only motors that meet the defined criteria.

Understanding the Results Table

The results table includes key motor parameters such as:

• Mechanical dimensions
• Motor constant (Km)
• Torque constant (Kt)
• Torque values
• No-load speed
  ‍

The table can be sorted by any column.

For example, if maximizing torque efficiency is critical, you can sort by motor constant (Km) to identify the most efficient solution within your constraints.

In this example scenario, the STM-75-20 Max with 8Y winding emerges as the most suitable option after sorting.

4. Evaluating Continuous Torque

On the right-hand side of the selector, you can see the expected continuous torque at the selected cooling level.

This value can be adjusted depending on your thermal conditions.

If the available continuous torque does not meet your system requirements, further filtering is required - this is where Advanced Mode becomes essential.

5. Using Advanced Mode for Performance Optimization

When switching to Advanced Mode, additional fields become available.

For example, you can:

• Define a minimum required continuous torque.
• Set a maximum continuous current.
• Specify a minimum no-load speed.
  ‍

Dynamic Parameter Behavior

Certain parameters adapt automatically based on your inputs:

• Maximum speed depends on the selected supply voltage.
• Current draw depends on the required torque.
  ‍

This dynamic behavior allows you to:

• Understand system trade-offs.
• Evaluate electrical and thermal feasibility.
• Optimize for performance or efficiency.
  ‍

If no motors match your criteria, consider adjusting limiting parameters (such as outer diameter or torque requirements) to explore alternative solutions.

6. Finalizing Your Motor Selection

Once you identify the motor that best fits your requirements, you can:

7. Best Practices When Using the Product Selector

To get the most accurate results:

• Start with hard physical constraints (diameter, length, mass).
• Then optimize for performance (torque, speed, efficiency).
• Review continuous torque under realistic cooling assumptions.
• Use Advanced Mode to validate electrical limits.
• Revisit constraints if no results appear.
