Operating instructions for the BRUSHLESS DR. SPEED motor series
Congratulations on your choice of a GM-Racing BRUSHLESS DR. SPEED motor; this is an innovative product of the highest quality.
These motors have been developed and manufactured to be extremely practical power plants, and provide outstanding performance in
radio-controlled models.
Please be sure to observe the following safety notes:
•
Read right through the operating instructions before you attempt to run the motor for the first time. These motors must always be
operated in conjunction with a suitable speed controller designed for brushless motors (see main Graupner FS catalogue). It is not
possible to run the motors by connecting them directly to a power source, and any such attempt will completely ruin the motor.
•
The motor may only be run when mounted securely in a model. Take care that no foreign bodies, dirt or damp get inside the
motor through these openings. As soon as a drive battery is connected, there is a chance that the motor will burst into life (e.g.
through an operating error or an electrical fault). This means: when a battery is connected, proceed with the greatest caution.
•
An electric motor, particularly when fitted with a gear, propeller (aircraft or boat), is capable of causing serious and possibly lethal
injury. Initial test runs should always be carried out without the gear or propeller fitted.
•
The motor should only be run in situations where the possibility of personal injury and damage to property can be eliminated. The
only area where persons may safely stand when the motor is running is behind the rotational plane of the propeller. Please
also observe the safety notes included with the propeller. If the motor should be damaged (e.g. due to mechanical or electrical
defect, damp etc.) do not use it again, as the motor could suddenly fail at any moment.
•
These motors should only be used in circumstances where no discharge of static electricity can occur.
•
These motors should be powered only by typical batteries used in modelling, with a maximum capacity of 5.0 Ah (see motor label
for permissible nominal voltage, e.g. 7,2 V), and must be operated in conjunction with a suitable speed controller. It is not
permissible to run the motor from a mains power supply. On no account connect the motor electrically to a 230 V AC mains power
source.
•
The motor's use in man-carrying aircraft or other vehicles is prohibited.
•
Read the operating instructions supplied with the brushless speed controller before connecting the motor to the controller.
Installing and operating the motor
- Installation:
If you are installing the BRUSHLESS DR. SPEED motor by the front motor plate (36 mm Ø), it is essential to note that the maximum
permissible screw depth is 4 mm.
When you have installed the motor, carefully turn the output shaft or the wheels of the vehicle through at least one full turn by hand, to
check that there is no obstruction. If the motor screws are too long, they will foul the rotor and the magnets and/or the winding; this
invalidates the motor's guarantee, and also that of the speed controller.
Over-long screws may also damage the motor winding Use M3 retaining screws, spaced about 25 mm apart.
Caution: be sure to use steel screws of the correct length (e.g. M3 x 6, if the motor mounting plate is at least 2 mm thick). Do not use
shortened screws, as the cut end will damage the threaded holes in the front motor plate. Please note that any electric motor can be
ruined by excessive heat. BRUSHLESS DR. SPEED motors are safe at temperatures up to about 100°C, but the motor may be
damaged above this figure. For this reason it is always best to avoid high temperatures. Electric motors generate excessive heat when
they are overloaded. This may occur, for example, if the reduction ratio is extreme (motor pinion with too many teeth), if too large a
propeller is fitted, if the motor shaft is prevented from turning (motor stalled), or if the motor is run continuously for an excessive time If
you are in any doubt, it is always best to try a motor pinion with fewer teeth or a smaller propeller (aircraft or boat), and check the motor
temperature. The mini infra-red thermometer, Order No. 1963, is ideal for this.
We recommend that you install the receiver as far away as possible from the motor, speed controller and high-current cables. The aerial
must not be deployed immediately adjacent to the motor and its cabling. If this is not possible in a particular model, these components
should be shielded with aluminium sheet or foil. The cable length between motor and battery must not exceed 25 cm (including the
speed controller leads). The cables which are attached to the motor must never be extended, as this will cause interference to the RC
system, and may result in the total loss of the model.
A trailing or whip aerial improves the overall operational security of the RC system. If you still have problems with reception, you will
often find that the cause is an unfavourable combination of components, or an incompetent installation of the receiving system.
