Electrical Motors
Electric motors form the foundation of any motion control or robotic system. At Acrome, we specialize in two primary motor technologies—Brushed DC Motors and Stepper Motors—each selected for their unique strengths in dynamic motion and precise positioning. These motor types are optimized for a wide range of applications, from mobile robotic platforms to high-precision automation tasks in education, research, and industry.
Brushed DC Motors
Brushed DC motors are commonly used for applications that require continuous rotation, variable speed, and real-time feedback via encoders. These motors are favored for their simplicity, responsiveness, and ease of integration into educational and prototyping platforms.
Key Features:
Speed and direction control via duty cycle
Encoder-based feedback for precision control
Compact and cost-effective
Ideal for mobile robots, wheels, and motion demos
Integration:
Controlled using SMD Red controller
Encoder feedback supported via onboard inputs
Compatible with SMD Blockly, Python SDK, and Flutter App
Example Applications:
Two-wheel differential drive robots
Closed-loop speed control experiments
Obstacle avoidance using motor + distance sensor
Stepper Motors
Stepper motors are used in systems that require high-precision positioning. These motors rotate in discrete steps, offering accurate control without the need for feedback sensors. Stepper motors are ideal for educational mechatronics projects, CNC machines, and 3D printers.
Key Features:
Open-loop control with precise step angles
Reliable for repeatable motion tasks
Microstepping support for smooth operation
Suitable for linear or rotary motion
Integration:
Controlled using SMD Blue controller
Step/Direction/Enable pins used for control
Compatible with Arduino Gateway, Python SDK, and advanced robotic frameworks
Example Applications:
Linear actuator control with set distances
Multi-axis motion systems (e.g., XY plots)
Pick-and-place mechanisms
