The Mega Torque Planetary Encoder DC Geared Motor with Japanese Mabuchi compatible RS-775WC as base motor of 750RPM is a unique system which enables you to get the stall torque of the motor even while using the motor at lower RPM. For RPM starting from 0 to maximum rpm possible as per gear box ratio, you can achieve the stall torque of the motor. Using a simple DC motor it is not possible to achieve desired torque at lower speeds because as you vary the input provided to the motor drive the output power is reduced. However the Mega Torque Planetary Encoder DC Geared Motor along with the DC servo drive the encoder feedback is a unique system which will allow to achieve maximum rated torque at lower speeds along with perfect position and multimotor co-ordination. 42mm diameter planetary gearbox gives breaking torque upto 200kgcm. Rated torque of this motor is 39Kgcm at rated 600RPM. This motor has 13PPR encoder. This being a Quad Encoder requires 52 Pulses Per Revolution of the base motor. Gear ratio is 1:25. The magnet encoder coupled with the base motor is a quad encoder which provides 1300 Counts per Revolution (CPR).
This motor is perfect for accurate speed applications and multimotor robotic platforms where speed and position co-ordination is important. This motor serves for critical applications where two motors working at same speeds are important for the working of the system. Also it gives a very fine setting to achieve required speed control using the high number of counts which are available with the coupled encoder.
To control the position of the motor and the speed, our DC Servo Drive RMCS -2301 is recommended to be used with this.
DC SERVO MOTOR DRIVER 40V 20A W/T STEP/DIRECTION INPUT
This Drive makes it very easy to control the speed and position of the motor using step pulses and direction. The quad encoder feedback is to be provided to this drive which has a step multiplier in steps up till 8x. So for a waveform of 10kHz, you can generate 48,00,000 pulses per minute to drive the encoder motor. This is suitable for lower rpm motors which have a higher count per revolution (CPR). For higher RPM motors where gearbox ratios are lower, the multiplier settings can be set to 2x or 4x to achieve the desired count required. Hence the motor and drive along with a PWM and frequency control can provide a perfect solution for precision position and speed control system.

*We recommend current controlled drive of Max 20Amps to be used with this motor so that it will not damage the gearbox. Gearbox is as such robust but cannot sustain if the motor is stalled which is rare case only.
