24V BLDC Motor Guide – Innotec

The demand for 24-volt BLDC (Brushless DC) motors has exploded across industrial, mobile, agricultural, automation, and marine markets. As system designers migrate away from brushed platforms and inefficient low-voltage drives, the 24V BLDC architecture has become the universal standard for mid-power electric motion systems. Innotec’s 24V BLDC product line is engineered specifically for high-torque delivery, thermal stability, and long-life operation in harsh environments.

Why Engineers Choose the 24V BLDC Platform

A 24-volt electrical system provides an ideal balance of power capacity, wiring efficiency, and operational safety. Unlike 12V systems, which require extremely high currents to reach even modest mechanical output, 24V dramatically reduces copper losses and voltage sag. This increases efficiency, extends runtime, lowers heat buildup, and reduces conductor size throughout the machine.

Electrical Efficiency Advantages

  • 50% lower current compared to 12V for the same wattage
  • Reduced I²R (copper) loss improves thermal stability
  • Better compatibility with FOC (Field-Oriented Control) BLDC drives
  • Lower wiring complexity and reduced system weight

Mechanical Performance Advantages

  • Smoother torque delivery due to improved commutation headroom
  • Higher overload capability for pumps, wheels, conveyors, and augers
  • Support for sustained continuous torque loads
  • Better low-speed controllability compared to brushed DC motors

Understanding BLDC Torque Production

In a BLDC motor, torque is generated by the interaction of rotor magnets and the electromagnetic field in the stator. Torque is directly proportional to phase current and magnetic flux. Higher-grade magnets, greater copper fill, and optimized stator lamination geometry increase torque density. Innotec motors use precision-engineered stator designs to deliver high continuous torque without overheating.

Continuous vs. Peak Torque

BLDC motors operate within two primary torque envelopes:

  • Continuous torque – sustainable indefinitely without overheating
  • Peak torque – available during 60-minute or 15-minute overload conditions

Continuous torque defines the “true capability” of the motor. Peak torque should only be used for:

  • Acceleration
  • Short surge loads
  • Breaking static inertia
  • Intermittent high-pressure pump demands

Thermal Behavior & Duty Cycle Engineering

Heat is the number-one limiting factor in any permanent magnet motor. At 24V, high load currents can raise winding temperatures rapidly if the motor is not designed for proper dissipation. Innotec designs its motors with:

  • High-thermal-conductivity housings
  • Tight lamination stacks to minimize core loss
  • Optimized slot geometry to reduce eddy currents
  • High-temperature magnet adhesives and insulation

60-Minute Duty Ratings

Reflect sustained overload capacity before thermal equilibrium is reached.

15-Minute Duty Ratings

Reflect short-burst output such as lifting, pump spikes, or vehicle acceleration.

24V BLDC Motor Applications

The versatility of 24-volt BLDC motors makes them ideal for a wide range of engineering applications:

Mobile & Industrial Robotics

  • AGVs, AMRs, warehouse robots
  • Drive wheels & steering actuators
  • Precision robotic joints requiring low-speed torque

Pumps & Hydraulic Systems

  • Oil pumps, coolant pumps, fuel pumps
  • High-pressure pump drives with 15-minute overload demand
  • Innotec 24V pump motors

Marine Systems

  • Trolling motors
  • Bilge & circulation pumps
  • Electric propulsion assist

Material Handling

  • Conveyors
  • Lift systems
  • Automated gantries

Controller Pairing & Drive Electronics

To deliver full performance, Innotec recommends pairing 24V BLDC motors with sinewave, FOC-capable controllers. Controller features that improve performance include:

  • Hall-sensor or encoder feedback
  • High-current MOSFET stages
  • Regenerative braking support
  • High PWM frequency for silent operation
  • Configurable current-limit profiles

24V System Integration & Wiring Considerations

Proper wiring is essential for achieving full performance from a 24V BLDC motor. Voltage drop must be minimized, especially in long-run mobile systems.

Recommended Wiring Practices

  • Use oxygen-free copper cable
  • Minimize run length between battery → controller → motor
  • Use 24V-rated fusing on battery side
  • Ensure controller ground and system ground share low-resistance connection
