Customized 200W (1/4 hp) 3000 rpm BLDC motor kit operates at 24V/48V DC, with lower noise and higher start torque, the adding brake option, matching 3 phase brushless dc motor controller and planetary gearbox/ worm gearbox are available here. ATO recommends buying a set of BLDC motors, which is an economical solution in the long run.
FEATURES
- High performance and low consumption.
200W BLDC motor is three phase electric motor, which especially suited for application requiring higher efficiency and power density.
- Wide application range and good control effect.
Brushless dc motor works with a matching controller (ATO-BLD750) may achieve simple to complex control, turn from CW to CCW, and meet various communication requirements (RS232, RS485, CAN, etc.). BLDC controller can be controlled through 0-5VDC analog signal to adjust the speed.
- Wide control speed torque range.
Brushless dc motor works with a gearbox (choose planetary gearbox with gear ratio from 4:1 to 200:1 or worm gearbox with gear ratio from 7.5:1 to 100:1) effectively reduce the motor's speed and moment of inertia to increase torque in your application, because the gearbox can control the start/stop and change speed in time.
- Low noise and smooth operation.
Brushless dc motor has no brushes, no sparks will be generated during operation, which greatly reduces friction.
- Good protection performance and continuous duty (24/7).
1/4 hp (200W) BLDC motor kit adopts a new type of sealing device, which has good protection performance and strong adaptability to the environment, and works continuously in harsh environments such as corrosion and humidity.

SPEED-TORQUE CURVE

- Instantaneous maximum torque line
The maximum torque momentarily impacts the load when the motor is started.
Beyond this torque, the over-current protection of the driver will cause the motor to stop.
- Short time operation area
The motor can run at a short time within this torque range at different speeds.
If the operation time is too long, the motor will generate heat, which may cause the motor to stop or burn.
- Rated operating torque line
The rated torque of motor running at different speeds, and the motor can run for a long time at this torque.
- Continuous operating area
When the motor rotates at different speeds, it runs continuously in this corresponding zone.

TIPS: Why Brushless DC Motor is Better Than Brushed DC Motor?
Brushless DC motors are applied to replace the traditional brush motors in forklifts, sweeping cars, sightseeing cars, electric buses and other battery cars, the motor capacity can be reduced by a level, the volume reduced by 2/3, the weight reduced by half and the battery capacity can be doubled, which gives the motor high climbing power with a starting torque up to 400%, you can start in the slope.
Brushless DC motors do not require to be maintained and repaired, and its operating efficiency is about 30% higher than brush DC motors, while what is more valuable is that it uses square wave drive (intermittent power), the current duty cycle is very low (unlike brush DC motors consuming continuous current), thus providing the time for the lead-acid battery to repair the electrode, thus extending the battery capacity by about 30% compared to a brush DC motor, that is, using a brushless DC motor to drive the endurance than a brush DC motor can be doubled or so.
