Mac Motor is a High Power, High Torque, Geared Hub Motor intended for Spoked Bicycle wheels

from 16" to700C.Rated Output power is typically between 500 to 1000W depending upon the motor winding

selected and the operating voltage. An internal 5:1 planetary gear with clutch is implemented.New stronger

Composite Gears are now standard on the 500W-1000W motors to ensure a long trouble free life.The gear

reduction allows the motor to spin at a higher and more efficient rpm greatly improving the starting torque and

hill climbing ability when compared with comparable Direct Drive motors, whilst also being smaller and lighter

than a comparable DD motor.The clutch offers minimal drag when not under power.Unlike the majority of geared

motors on the market, the Mac high power motor is built for the high power demands of the US market, not the

highly restricted EU market.The slower wound versions could still be used and stay within the EU speed limit, for

those requiring more hill climbing ability than the typical small power motors can offer.

 

Specifications
Mac High Power and High Torque, Geared Hub Motor Data

Note:Technical specifications and outline drawings can be customized according to your requirements.

As a guideline, you can expect approximately the following technical speed for the above windings:

6 turn high speed motor                              - 400rpm loaded at 36V, 520rpm loaded at 48V

8 turn standard motor                                 - 320rpm loaded at 36V, 400rpm loaded at 48V

10 turn torque motor                                  - 255rpm loaded at 36V, 320rpm loaded at 48V

12 turn low speed extra torque motor          - 200rpm loaded at 36V, 250rpm loaded at 48V

Features

Key Features of Mac Upgraded Hub Motor

- New, fresh design;

- Various axle lengths available (135mm standard, 170mm for fat tire);

- Temperature sensor (optional);

- Higher grade stator laminations (0.35/0.27mm), for improved efficiency and reduced heat;

- Freewheel or Splined Cassette;

- Improved clearance for Disc Brake Caliper (19.5/20mm).

Mac motor uses a 32 magnet, 16 pair pole motor unlike the vast majority of Geared motors on the Market

which use an 8 pair pole motor.This further improves torque, but does mean that the electrical rpm

or commutation frequency is higher than typical geared motors and much higher than Direct-Drive motors, so

some care with controller selection is required.The available space for the disk is a little limited at 15mm

between the side casing and the inner face of the disk, so some care when selecting a suitable caliper is

required or some spacing of the disk away from the side cover and possibly modification of the caliper mounting

may be required for some models of disk brake caliper.Mac rear motor allows both disk brake and 7 speed

freewheel to be used on the standard 135mm dropout and 170mm dropout for fat tire, which many of the small

power geared motors cannot achieve.Mac front hub motor is now available with disc brake and is compatible

with standard 100mm fork dropout.
