| These motors are a marvel of modern engineering! They combine rare earth magnets with a coreless design to produce high torque motor with diameters ranging from 4mm to 36mm. They feature a sintered bronze bearing to support the output shaft. Originally designed for vibration functions in mobile phones, these come without the weight and are finding increasing applications in models, miniature toys, medical instruments and many miniaturised consumer applications. |

Micropump patented electromagnetic drives use rare earth magnets to increase motor torque capabilities while reducing total pump/drive package size. Surface mount technology improves reliability and enables higher efficiency motor performance. Variable speed electronic controllers offer thermal and overload protection with the option of a 0-5 VDC input signal, a 4-20 mA current loop, or a manually controlled drive. Closed-loop speed control allows for quick and easy setting of speed.

| All AMETEK brushless DC motors and blowers require a motor/blower controller to operate. Many of these AMETEK BLDC motors and blowers feature a built in, integrated controller that takes the DC input from a power supply or battery and processes it into phase drive signals that are used to commutate the motor. Motors and blowers that require low voltage DC input (11 to 52 volts) that do not come equipped with an integrated, onboard controller, require one of the external controllers described in this section. |

The DECS 50/5 (Digital EC Controller Sensorless) is a new controller for driving brushless DC motors without Hall sensors.
Typical sensorless drives such as pumps and fan applications can now easily be created thanks to modern technology and expert integrated controlling algorithms. maxon's own in-house developed speed controller is particularly impressive through its performance, price and size.
As well as being a top performer, attractively priced and very small, the new amplifier's other key feature is that it can be easily adapted to specific requirements. The free choice of starting sequence is a major benefit, as it allows the attached motor to start up easily, even when the motor data or load ratios are unfavourable. The DECS 50/5 also provides control inputs for selecting motor direction, enable and braking. As usual, the necessary protective functions have all been fully implemented. An operating status display (LED) and speed monitor output complete the convenient control features. |

The Red Drive Controller is a compact (46x63mm) yet powerful motor driver and controller. It is designed to be used in conjunction with our dual channel encoder and wide range of low cost DC motors and gearboxes.
In combination with our unique graphical software and Serial Adapter units the Red Drive controller is easily programmed by the user. Both simple and complex sequences of motion can be undertaken with the user specifying how and when their motor will move. Full control is available over speeds, distances and direction. The unit is able to interact with switches, LEDs, buzzers and other user defined inputs and outputs.
The Red Drive software provides the user with an incredibly easy to use interface for defining all aspects of the controller. No complex programming is required, just a simple drag and drop flowchart style interface which uses real world values such as rpm and seconds. |

To control the speed of the DC motor gradually, smooth DC voltage across the armature of the motor needs to be regulated along with the fixed DC voltage across the Field winding in the case of the 4 wire DC motors. The DC drive featured here, generates the variable DC voltage using phase angle control technique incorporating Diode / SCR rectifier. The DC voltage across the armature winding can be smoothly varied using the potentiometer or using the external control signal of 4-20mA or (0-5)VDC. Models are available for 1/8HP to 5HP DC motors operating on 100VDC to 400VDC.
APPLICATIONS
Suitable for small machines in Plastic, Packaging and Pharmaceutical industries where smooth and steady control over DC motor is required
