EXAMPLE OF SELECTION IN CONTINUOUS OPERATION

Application requested data:

- Operating speed : NR = 4000 rpm (working point)

- Operating torque : TR = 1.4 mNm (working point)

- Max. voltage supply : Umax = 10 VDC

- Max. current supply : Imax = 0.2 A

- Ambient temperature : Ta = 25 °C

- Motor type : DC coreless motor

- Max. motor length : Lmax = 35 mm

- Max. motor diameter : φmax = 13 mm

Selection Guide

Step 1. Motor type and physical dimensions

Consider motor technology and physical dimensions when selecting

the potential candidates from the catalog. In this example

coreless motors up to SCL12-30 series (φ= 12.5 x L = 32 mm)

will be considered.

Step 2. Working point and max. continuous values

Knowing the motor working point, NR = 4000 rpm and TR = 1.4

mNm, select from datasheets all motors where working point is

inside of the continuous operating area. In this example SCL12-22

(max. continuous torque 1.6 mNm) and SCL12-30 series will be

considered (max. continuous torque 2.09 mNm).

Step 3. Voltage and current supply

Verify if selected motors are able to operate at the working point

with the available max. current and voltage supply.

Step 4. Motor performance analysis

Once the motors operatable at the working point have been

defined performance around the working point can be calculated.

- Current absorbed at working point, IR [A]

- Motor output power at working point, Pout [W]

- Motor efficiency at working point, h [%]

Note: In this catalog only standard coils are shown. If desired,

Namiki can provide different coils to meet specific working points.

Please consult our sales section for details.

Step 5. Thermal considerations

The described procedure is generally suitable for most of the

cases. However, if more accurate calculation is required then

thermal behavior at working point can be considered.

- Motor coil temperature at working point, Tc [°C]

- Motor coil resistance at working point, Rwp [W]

limits.

Gearhead selection

If a motor-gearhead combination is requested, before proceeding

with step 2, calculate working point at motor output shaft. For

gearhead selection, where life expectancy is concerned, it is

important to choose a product with an output torque higher than

that required by the application and to operate the motor, by

selecting the appropriate reduction ratio, at a continuous speed

lower than the gearhead maximum recommended input speed.

DC motor performances are generally defined using the

relationship between torque and the other major 4 parameters

(current-I, speed-N, output power-P and efficiency-h) as illustrated

in figure 1. Speed-N and current-I curves are directly related to

torque. (I) is in proportion to torque while (N) is inversely

proportional. The peak of output power (P) and efficiency (h) exist

at different torque points as shown in figure 1. Output power (P)

curve draws a parabola variable by Ts, while efficiency (h)

decreases straight down beyond the peak.

As Pmax exists at half the starting torque (Ts/2) point and

maximum efficiency at a much lower point, both peaks can not be

obtained at the same time. This means that it is not possible to

operate a motor simultaneously at maximum power and efficiency.

Motor Curves

In this catalog only the speed-N and current-I versus torque curves

are illustrated, while for output power-P and efficiency-h the

maximum values reached when the motor is supplied with nominal

voltage are indicated. In addition, for easy motor selection the

working area in continuous operation is also displayed as

illustrated in figure 2.

Life expectancy

Since product life is strongly affected, not only by the output speed

and torque, but also by the environmental conditions (temperature,

humidity, vibration, etc.), operating mode (linear/switching drive

circuit, start/stop and CW/CCW operation) and shaft load (axial

and radial load), tests in the application are always recommended.

The working area is defined by the maximum continuous motor

speed and torque (for sensorless brushless motors the minimum

speed is also considered). An ideal motor life should be achievable

in normal conditions where the shaft loads are not exceeded if the

motor is operated within this area. Since the working area is

independent of the motor voltage supply, to operate in all working

area it is necessary to select the appropriate voltage supply. For

example when the SBL22-3727 brushless motor is supplied with

24V, no-load speed is 4825 rpm, see figure 2. To operate at higher

speed it is necessary to increase the voltage supply. Since no-load

speed (No) and starting torque (Ts) are both in proportion to

voltage, speed versus torque curve reacts parallel to voltage, while

speed/torque gradient (slope) remains constant as shown in figure

3, and output power vary as shown in figure 4.

SSD04

SSD04

Description

SSD04 is a 3-phase sensorless drive circuit designed to operate brushless motor SBL02-06 and SBL04-08 exclusively. The operating voltage

can be adjusted by VR trimmer and motor shaft direction can be reversed by connecting CW/CCW input to Vcc, if not connected the SBL02-06

runs CW while SBL04-08 CCW. FG (Frequency Generator) output provides a pulse per motor revolution. Internal thermal protection circuit

included.

SSD22

SSD22

Description

SSD22 is a 3-phase sensorless drive circuit designed to operate brushless motor SBL22-37 exclusively. The desired motor speed is set by

selecting the appropriate voltage supply, VCC. CW direction is obtained by connecting CW/CCW input to VREG, if not connected the motor

runs CCW. FG (Frequency Generator) output generates 3 pulses per motor revolution. The LOCK output provides in normal operation an high

logic level "1", in motor stall condition a low logic level "0". Internal thermal protection circuit included.
